Analysis of Effects of energy and pulse width on underwater Lidar system

摘要

Lidar is an important equipment for the accurate detection of underwater targets.In lidar measurements of underwater target, the energy and width of the laser pulse will affect the results when using PMT as receiver, which has been proved by data processing and analysyses. To avoid the effect and enhance the accuragy of underwater, many methods such as controling the energy of the laser pulse, reducing the pulse width are taken. The experiment results of underwater target measurement are discussed.
