Abstract

The present disclosure is directed to imaging LiDARs that can include a FPSA beam scanner and a lens. One or both of the FPSA beam scanner and lens can be moved laterally to increase a lateral resolution of the LiDAR system. Some embodiments can include a microlens disposed between the FPSA beam scanner and the lens. Methods of use are also provided.
