Patent ID: 7241982

Claim:
An optical image transmitting system, comprising: optical image transmitting means for producing a plurality of optical image information beams that represent a plurality of optical image information and include light beams having different frequencies, superimposing the plurality of optical image information beams into signal light, and emitting the signal light; and optical image receiving means for receiving the emitted signal light and selectively detecting the optical image information beams based on the frequency difference; wherein the optical image transmitting means includes: image producing means for producing the plurality of optical image information beams; frequency modulating means for modulating frequencies of the plurality of produced optical image information beams by different amounts; optical image information superimposing means for superimposing the plurality of optical image information beams whose frequencies are modulated to produce the signal light; and transmitting means for transmitting the produced signal light to the optical image receiving means; wherein the image producing means includes a plurality of display means for displaying an image and light sources for emitting a light beam to the displayed image; and the optical image information is created by using the image irradiated with the light beam from the light source.
