Vibrated polarizing beam splitter for improved return light detection

Abstract

Systems, methods, and computer-readable media are disclosed for a vibrated polarizing beam splitter for improved return light. An example method may involve emitting, by an emitter, a first light pulse. The example method may also involve reflecting, by a polarizing beam splitter in a first position, the first light pulse, wherein the polarizing beam splitter is at a first angle of incidence in the first position. The example method may also involve adjusting, subsequent to the polarizing beam splitter reflecting the first light pulse, a position of the polarizing beam splitter from the first position to a second position, wherein the polarizing beam splitter is at a second angle of incidence in the second position. The example method may also involve transmitting, by the polarizing beam splitter, a return light pulse through the polarizing beam splitter, the return light pulse based on the first light pulse. The example method may also involve detecting, by a detector, the return light pulse.
