The Theoretical Analysis of the Affect about Scatter to Laser Underwater Imaging Precision

The technology of laser underwater imaging has obtained some productions in the world, present- synchronous scanning tech- nology and range- gated rechnology are mostly applied now.Water quality of our country’s offing is muddy,so scattering phenomena is severity.This article analyses the affect about scatter to imaging precision on the base of researching the transmission characteristic of laser underwater imaging,in order to gain wide visual angle,whole depth of field and high definition.
