Abstract
Systems, methods, and computer-readable media are disclosed for systems and methods for improved LIDAR return light capture efficiency. One example method may include emitting, by an emitter, a first light pulse in a first path. The example method may also include transmitting, by a polarizing beam splitter in the first path and aligned with an aperture of a reflective element, a portion of the first light pulse, wherein the reflective element is disposed of in the first path. The example method may also include reflecting, by a reflective surface of the reflective element, a second light pulse in a second path, the second light pulse including a return pulse based on the first light pulse being reflected from an object. The example method may also include detecting, by a detector, the detector disposed in the second path of the second light pulse.
