Abstract:
1. A system for free space, high-speed optical communication, comprising: a transmitter portion comprising a wide band, pulsed light source that emits light beam pulses, a first spectral element for spatially dispersing the light beam pulses, a first electro-optical spatial light modulator for encoding the spectral domain of the light beam pulses from the pulsed beam of light, a second spectral element for recombining the dispersed, encoded light into single optical beam pulses, and a second electro-optical spatial light modulator for modifying the transverse coherence of the collected and encoded light beam pulses, a receiver portion comprising a third spectral element for dispersing the encoded and modified pulsed light beam pulses, and a photosensor array for detecting the dispersed, encoded, modified light beam pulses, and a data processing element for decoding and processing data received from the photodetector at a rate ‘R’ wherein R≧1 Gibabits per second (Gbps), and a feedback element in communication with said second spatial light modulator and said photodetector for maintaining an optimal value of a coherence radius, r
