Abstract

Slit Streak Tube Imaging Lidar (STIL) is a promising imaging system as its high frame rate and good image quality. As its important applications, the depth under the water to detect a underwater target near the coast is less than 20m. It can effectively indemnify the safety of ships. We use a Slit Streak Tube Imaging Lidar, including a laser whose wavelength is 532nm and the energy of one pulse is 20mJ. Through the outfield experiment on the sea, we discussed the optical properties of the target surface and distinguished two targets with the distance more than 10cm in one image. Also we get the imaging of the target which is 6m deep in the sea. We calculated the relationship between lidar detectable range and laser power in different attenuation. It will provide the basis for the future experiments.
