Abstract

Embodiments of the disclosure provide a design method for a LiDAR scanning mirror. The design method may include receiving, by a communication interface, design parameters of the LiDAR scanning mirror. The design method may further include setting, by at least one processor, an initial value and a step size for each design parameter. The design method may also include adjusting the design parameters according to the respective step sizes. The design method may additionally include computing one or more mirror performance indexes, by the at least one processor, by applying a Finite Element Analysis (FEA) model to the adjusted design parameters. The design method may further include determining that the mirror performance indexes meet a predetermined target performance. The design method may also include providing, by the at least one processor, the adjusted design parameters and the mirror performance indexes for making the LiDAR scanning mirror.
