PURPOSE: To realize a voice, image and data communication equipment using light provided with a function superimposing voice, image data onto a light from a light source through the use of a coil so as to modulate the light into a modulated light, sending the light with the medium of an optical fiber or space and receiving and demodulating the modulated light by a solar battery. CONSTITUTION: A transmission section is featured to superimpose voice, image and data onto a light from a light source 1 through the use of a coil so as to form a modulated light. A reception section is featured to receive and demodulate a received modulated light with a solar battery 2. A bundle 3 of optical fibers without sheath are used to interconnect the transmission section and the reception section to allow the state of propagation of light through the inside of the optical fibers to be observed. When space is used as a medium, the bundle 3 of the optical fibers is removed and a convex lens 4 is provided on the front face of a light source 1 and the front face of a solar battery 2. Thus, the communication range is adjusted. |
