Image phase compensation and real-time holography by four-wave mixing in optical fibers [PDF]
, 1978 It is proposed that real-time holography can be performed inside multimode fibers (or optical waveguides) using four-wave optical mixing. Of particular interest is the generation of complex-conjugate replicas of input fields for image transmission and ...
