Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail.

Computer monitors produce electron beams from the CRT to display the screen, and collide with fluorescent materials deposited on the surface of the CRT to produce pixels in small pixel units, and display the screen using a combination of these pixels. At this time, light is generated by electrons colliding with the fluorescent material, and the generated light is emitted outside the CRT. By applying this principle, the pattern (screen) of the emitted light of the CRT is adjusted according to the desired data to change the size and generation period of the light to generate light that responds to the desired data.

The optical signal receiving unit receives the light in a form close to the monitor. To receive an optical signal, a lens-integrated photodiode is applied and used for peak photodetection to convert the light signal into an electrical signal.
