The present disclosure is drawn to systems of enhancing contrast of LED lighting, including two subsystems. A light-transmitting subsystem can include an LED light source, a first reference oscillator to receive a reference signal broadcast from a remote source, and a synchronous modulation and power system to cause a stream of modulated light-signal pulses to be emitted from the LED light source in synchronous correlation with the reference signal. A light-receiving subsystem can include a light imager to synchronously receive the stream of modulated light-signal pulses, a second reference oscillator to receive the reference signal broadcast from the remote source, and a synchronous demultiplexing system to convert the stream of modulated light-signal pulses to a stream of synchronous digital images in synchronous correlation with the reference signal. A demodulation image processor can be used to process and generate enhanced contrast display imagery.
