AI Technical Summary
Existing lidar sensors suffer from high precision requirements in optical alignment, low production yield, and susceptibility to external factors, leading to deterioration in sensing accuracy and resolution.
By designing the layout of the light source array and controlling the drive system, a preset alignment coefficient is used to relax the alignment tolerance margin, enabling flexible alignment between the light source and the photodetector. This includes the (M+a)N or (M_i+a)(N_j+b/2) structural layout design of the light source array, and synchronous operation is performed by setting the activation mode through the controller.
It improves the yield and reliability of lidar sensors, reduces production time, reduces performance degradation caused by external factors, and enhances the stability of sensors in various environments.
