Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries (all of which are wholly owned) and have been prepared in conformity with U.S. generally accepted accounting principles (“US GAAP”) applicable to interim periods. All intercompany balances and transactions have been eliminated in consolidation. The presentation of certain prior period amounts has been reclassified to conform with current year presentation. The unaudited condensed consolidated financial statements include all adjustments (consisting of only normal recurring adjustments) necessary for a fair statement of the results of operations for the periods shown. The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements as of and for the year ended December 31, 2022 and the notes related thereto, included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 24, 2023. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by US GAAP. Certain information and note disclosures normally included in the audited financial statements prepared in accordance with US GAAP have been condensed or omitted from this report, as is permitted by applicable rules and regulations. The results of operations for any interim period are not necessarily indicative of the results to be expected for the year ending December 31, 2023 or for any other future years or interim periods. On April 6, 2023, the Board of Directors approved a one-for-10 reverse stock split and a corresponding reduction in authorized shares of common stock (the “Reverse Stock Split”). On April 20, 2023, the Company filed with the Secretary of State of the State of Delaware a Certificate of Amendment to its Certificate of Incorporation to effect the one-for-10 Reverse Stock Split of the Company’s common stock and a corresponding reduction in authorized shares of common stock. The par value of the Company’s common stock was not adjusted as a result of the Reverse Stock Split. All share and per share amounts and related stockholders’ equity balances presented herein have been retroactively adjusted to reflect the Reverse Stock Split.
Revenue Recognition	Revenue Recognition The Company recognizes revenue when a customer obtains control of promised products or services. The amount of revenue recognized reflects the consideration that the Company expects to be entitled to receive in exchange for these products or services. To achieve the core principle of this standard, the Company performs the following five steps: 1) Identify the contract with a customer A contract with a customer exists when the contract is approved, each party’s rights regarding the product or services to be transferred and the payment terms for the product or services can be identified, it is determined that the customer has the ability and intent to pay and the contract has commercial substance. The Company applies judgement in determining the customer’s ability and intent to pay, which is based on a variety of factors, including the customer’s historical payment experience or, in the case of a new customer, credit and financial information pertaining to the customer. Accounts receivable are due under normal trade terms, typically three months or less. 2) Identify the performance obligations in the contract Performance obligations promised in a contract are identified based on the product or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the product or service either on its own or together with other resources that are readily available from third parties or from the Company, and are distinct in the context of the contract, whereby the transfer of the product or services is separately identifiable from other promises in the contract. 3) Determine the transaction price The transaction price is determined based on the consideration to which the Company expects to be entitled in exchange for transferring product or services to the customer. Royalties from the license of IP are included in the transaction price in the period the sales occur. Other forms of variable consideration are included in the transaction price if the Company judges that it is probable that a significant future reversal of cumulative revenue under the contract will not occur. None of the Company’s contracts contain a significant financing component. All taxes assessed by a governmental authority on a specific revenue-producing transaction collected by the Company from a customer are excluded from the transaction price. 4) Allocate the transaction price to performance obligations in the contract If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price (“SSP”). In the three months ended March 31, 2023 and March 31, 2022, the Company did not have a material volume of contracts that required the allocation of transaction price to multiple performance obligations. 5) Recognize revenue when or as the Company satisfies a performance obligation Revenue is recognized at the time the related performance obligation is satisfied by transferring the promised product or service to a customer. Product revenue The majority of the Company’s revenue comes from product sales of lidar sensors to direct customers and distributors. Revenue is recognized at a point in time when control of the goods is transferred to the customer, generally occurring upon shipment or delivery dependent upon the terms of the underlying contract. Product sales to certain customers may require customer acceptance due to performance acceptance criteria that is considered more than a formality. For these product sales, revenue is recognized upon the expiration of the customer acceptance period. For custom products that require engineering and development based on customer requirements, the Company recognizes revenue over time using an output method based on units of product shipped to date relative to total production units under the contract. Amounts billed to customers for shipping and handling are included in revenue, and the Company has elected to recognize the cost of shipping activities that occur after control has transferred to the customer as a fulfillment cost rather than a separate performance obligation. All related shipping costs are accrued and recognized within cost of revenue when the related revenue is recognized. Services The Company’s services revenue consists primarily of product development, validation services and providing maintenance services under our extended warranty contracts. The obligation to provide services is generally satisfied over time, with the customer simultaneously receiving and consuming the benefits as the Company satisfies its performance obligations. For product development and validation service projects, the Company bills and recognizes revenue as the services are performed. For these arrangements, control is transferred over as the Company’s inputs incurred to complete the project; therefore, revenue is recognized over the service period with the measure of progress using the input method based on labor costs incurred to total labor cost (“cost-to-cost”) as the services are provided. The revenue from the sale of extended warranties is recognized over the warranty period on a ratable basis as the Company stands ready to provide services as needed. Licenses The Company licenses rights to its IP to certain customers and collects royalties based on customer’s product sales. IP revenue recognition is dependent on the nature and terms of each agreement. The Company recognizes license revenue upon the later of (a) delivery of the IP or (b) commencement of the license term if there are no substantive future obligations to perform under the arrangement. Revenue for licenses to future technology developed on a when-and-if -available basis is recognized straight-line over the license period as long as customers continue to have access to the future technology. Royalties from the license of IP are recognized at the later of the period the sales occur or the satisfaction of the performance obligation to which some or all of the royalties have been allocated. Product Warranties The Company provides standard product warranties for a term of typically one to two year depending on a product to ensure that its products comply with agreed-upon specifications. Standard warranties are considered to be assurance type warranties and are not accounted for as separate performance obligations. The Company also provides service type extended warranties for an additional term ranging up to two additional years. For service type extended warranty contracts, the Company allocates revenue to this performance obligation on a relative standalone selling price basis and recognizes the revenue on a ratable basis over time during the effective period of the services. Costs to obtain a contract The Company expenses the incremental costs of obtaining a contract when incurred because the amortization period for these costs would be less than one year. These costs primarily relate to sales commissions and are expensed as incurred in sales and marketing expense in the Company’s consolidated statements of operations and comprehensive loss. Remaining performance obligations Revenue allocated to remaining performance obligations represents the transaction price allocated to the performance obligations that are unsatisfied, or partially unsatisfied. It includes unearned revenue and amounts that will be invoiced and recognized as revenue in future periods and does not include contracts where the customer is not committed. The customer is not considered committed where they are able to terminate for convenience without payment of a substantive penalty under the contract.
Investments	Investments The Company considers investments with an original maturity greater than three months and remaining maturities less than one year to be short-term investments. The Company classifies those investments that are not required for use in current operations and that mature in more than 12 months as long-term investments. The Company classifies its investments as available for sale and reports them at fair value, with unrealized gains and losses recorded in accumulated other comprehensive loss. For investments sold prior to maturity, the cost of investments sold is based on the specific identification method. Realized gains and losses on the sale of investments are recorded in other income, net in the condensed consolidated statement of operations.
Amazon Warrant	Amazon Warrant The Amazon Warrant (as defined in Note 7) is accounted for as an equity instrument. To determine the fair value of the Amazon Warrant on its issuance date, the Company used the Black-Scholes option pricing model. For awards granted to a customer, which are not in exchange for distinct goods or services, the fair value of the awards earned based on service or performance conditions is recorded as a reduction of the transaction price. Accordingly, when Amazon makes payments and vesting conditions become probable of being achieved, the Company records a non-cash stock-based reduction to revenue associated with the Amazon Warrant, which is calculated based on the fair value of the Amazon Warrant shares as of the Velodyne Merger date.
Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Issued Accounting Pronouncements Not Yet Adopted The Company considers the applicability and impact of all ASUs. ASUs not referenced below were assessed and determined to be either not applicable or are not expected to have a material impact on the Company’s condensed consolidated financial statements.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject the Company to credit risk consist primarily of cash, cash equivalents, restricted cash, short-term investments and accounts receivable. Cash, cash equivalents, restricted cash and short-term investments are deposited with federally insured commercial banks. At times, cash balances in the U.S. may be in excess of federal insurance limits. As of March 31, 2023 and December 31, 2022, the Company had cash, cash equivalents and restricted cash with financial institutions in the U.S. of $113.4 million and $123.5 million, respectively. As of March 31, 2023 and December 31, 2022, the Company also had cash on deposit with financial institutions in countries other than the U.S. of approximately $4.1 million and $0.8 million, respectively, that was not federally insured. The Company generally does not require collateral or other security deposits for accounts receivable. To reduce credit risk, the Company considers customer creditworthiness, past transaction history with the customer, current economic industry trends, and changes in customer payment terms when determining the collectability of specific customer accounts. Past due balances over 90 days and other higher risk amounts are reviewed individually for collectability. Based on management’s assessment, the Company provides for estimated uncollectible amounts through a charge to earnings and a credit to valuation allowance. Balances that remain outstanding after the Company has used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable.
