Abstract

Currently, underwater divers become one of the main forces for underwater rescue and exploration. In order to extend the search distance of the underwater divers, miniaturized underwater optoelectronics imaging system turns out to be the main direction of development in and abroad. On the basis of introduction to some optoelectronic imaging advices for underwater divers, this paper designs a set of handheld underwater observation instruments used for underwater rescue and exploration, using the range-gated imaging technology, to eliminate the bad influence efficiently which is caused by the water backscatter. This paper gives some introductions about principles, system construction, and control system part, and makes a brief analysis of the characteristics and prospect of the system.
