DEVICE FOR UNDERWATER WIRELESS COMMUNICATION BY OPTICAL CHANNEL

摘要

A useful model refers to the technique of underwater communication. The device for underwater optical communication for divers contains a telephone-microphone headset (TMG), associated with it a button block that allows temporarily disconnecting the transmission channel and adjust the volume of communication, and a processor unit with an optical transceiver system containing collimating and focusing lenses of the transmitter and receiver channel, a grating Bragg filtering solar radiation, sealed protective glasses, the transmitter driver unit and the automatic gain control unit whose inputs and outputs are connected to the block quarrel. The device provides high quality of communication and speech recognition of the interlocutor under water, has small dimensions and has the ability to mount both on the helmet of the diving equipment and on the hand of the diver. Improved communication quality and recognition of the interlocutor under water is achieved. 1 yl.
