Ten thousand meter underwater high-definition video live broadcast

The exhibit introduces how wireless blue-green light communication technology plays a role in live diving of deep-sea submersibles, and why blue-green laser communication technology is used for deep-sea communication. Rotate the button to adjust the interference level of different colored lasers on the live broadcast screen, and feel the impact of different lights on signal transmission. Wireless blue-green light communication technology plays an important role in deep sea exploration, especially in the live streaming of the "Striver" submersible. The advantages of underwater optical communication: Although the communication distance of underwater optical communication is not as good as acoustic communication, it is farther than wireless communication, and the data rate far exceeds these two. Advantages of blue-green light communication: Light with wavelengths between 450-570 nanometers (blue and green light) has the lowest absorption coefficient in water and can achieve higher data rates. Blue green laser communication combines the advantages of laser communication and blue-green light communication.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
