Underwater bi-directional wireless image data communication system based on illumination diffusion support

An underwater bi-directional wireless image data communication system based on illumination diffusion support comprising:

• a wireless image communication device comprising a comparison processing device for converting an image signal about image data photographed by an image device or input from the image device into an electrical signal, a light emitting unit for receiving the electrical signal from the comparison processing device and converting the electrical signal into an optical signal to output light, and a light receiving unit for receiving an external optical signal and converting the external optical signal into an electrical signal to be output as an image;
• and
• an illumination diffusion device for providing illumination having higher intensity than illumination of the light emitting unit to a communication area between wireless image communication devices when underwater bi-directional wireless communication is performed using the wireless image communication devices.
