Abstract

A method and apparatus using a holographic storage medium for direct transmission of an optical image which can compensate for distortions occurring during transmission of the image. An apparatus for direct transmission of an optical image in accordance with the present invention includes a first lens 6c for collimating light from an optical image into a first parallel beam; a transmission medium 2a for transmitting optical signals; a holographic storage medium 1a containing information on distortion of said transmission medium 2a; a mirror 7; a second lens 6d for focusing said first parallel beam passing through said holographic storage medium 1a onto the surface of said mirror 7 and collimating a beam reflected from said mirror 7 into a second parallel beam, the direction of propagation of said second parallel beam being opposite to that of said first parallel beam; a third lens 6a, 6b for directing a phase conjugate wave reproduced from said holographic storage medium 1a by said second parallel beam to said transmission medium 2a; and an image display 4 for displaying said optical signals transmitted through said transmission medium 2a.
