PURPOSE:To prevent mixture of noise and modulation and demodulation distortion, by transmitting optical information to a reception side with an optical fiber bundle and reproducing picture through the direct incidence of the optical signal on a photographic paper. CONSTITUTION:The surface of an original picture 1 is illuminated along a straight line X with high illumination. Further, one end of an optical fiber bundle 6 with a lot of optical fibers is arranged on a row and opposed to the original picture along the straight line X. A fiber 7 of the optical fiber bundle 6 is separated as a control and the tip is opposed to the original picture 1 at a location with a suitable interval from the straight line X opposite to the arrow P. A light transmitted in the optical fiber 7 is converted into a signal and applied to a controller 15. Since the optical information in the original picture is directly reproduced on a photographic paper without converted into an electric signal, no noise is mixed in the signal during transmission and no modulation/ demodulation distortion is received. |
