Systems of enhancing contrast of lighting can include a light-transmitting subsystem having a light source to emit a stream or light-signal pulses and an encoding circularly polarizing filter to optically encode the stream of light-signal pulses with circular polarization, and a light-receiving subsystem including a decoding circularly polarizing filter to optically decode the circular polarization of the stream of light-signal pulses and a light imager to receive the stream of light-signal pulses after being optically decoded by the decoding circularly polarizing filter. In another example, the system can include a polarimetric light imaging assembly, a light source to generate a stream of light-signal pulses directed at the polarimetric light imaging assembly, and a control system to synchronously control the light-signal pulses to be emitted from the light source in timed correlation with a component(s) of the polarimetric light imaging assembly.
