PURPOSE:To directly transmit a two-dimensional image, and also, to execute a long distance transmission by splitting two-dimensional image information by plural light beams each is different in wavelength, and transmitting it by wavelength multiplexing. CONSTITUTION:A multicolor light beam emitted from a light source 1 is radiated to a diffraction grating 3 by a lens 2 and split into monochoromatic light beams of lambda1-lambdaN. These light beams each different in wavelength are made incident by making them correspond to 1-to-1 to optical fibers arranged in one horizontal line of a fiber bundle 4 by using a lens 2', and N pieces of light beams lambda1-lambdaN pass through the other end of a two-dimensional shape of the fiber bundle 4 and radiated to each corresponding point of the original image 5. Subsequently, each light beam which has transmitted through the original image 5 is made incident on one end of an optical fiber 6 by a lens 2'', and the light beams of each point corresponding to each picture element of the original image 5 are emitted simultaneously from the other end, split by a diffraction grating 3' of a receiver and made incident on an optical fiber of a fiber 4', and rearranged to a position of the original picture element. |
