A LiDAR system includes a light source and an arrayed micro-optic configured to receive light from the light source so as to produce and project a two-dimensional array of light spots on a scene. The LiDAR system also includes receiver optics having an array of optical detection sites configured so as to be suitable for establishing a one-to-one correspondence between light spots in the two-dimensional array and optical detection sites in the receiver optics. The LiDAR system further includes a birefringent prism and a lens. The LiDAR system may also include a mask placed in the light path between the birefringent prism and the receiver optics. Alternatively, the LiDAR system may include a controller programmed to activate or deactivate each optical detection site.
