PURPOSE:To convert directly two-dimensional information into an optical signal in the way of two-dimension without scanning conversion by irradiating a parallel ray to a picture to be transmitted to convert the contrast of the picture caused by transmission or reflection of the ray into the strength of light. CONSTITUTION:The light from a light source 1 using a semiconductor laser having a single wavelength is formed into a parallel ray through an optical lens 2 and irradiated on a picture medium 3 to be transmitted. Then, the contrast of the picture is converted into the strength of light and the ray converged through an optical lens 4 is made incident to an optical fiber cable 5. The light propagated through the optical fiber cable 5 is converted into an electric signal by a photoelectric converter 6 comprising a CCD element or the like at the end and displayed or copied on a terminal device 7. |
