Imaging by Single-Slit Streak Tube Laser Lidar

Experiments on the range resolution measurement of a slit Streak Tube Imaging Lidar

“…By orienting the fan beam perpendicular to the vehicle track, the along-track dimension is sampled by adjusting the pulse repetition frequency (PRF) of the laser to the forward speed of the vehicle, thus sweeping out the three-dimensional ocean volume. rebuilding every frame of imaging, we can get 3D imaging and 2D intensity imaging of the target [8].…”

Experiments of ocean surface waves and underwater target detection imaging using a slit Streak Tube Imaging Lidar

“…The receiver is a streak tub camera which is an instantaneous optical device. The reflected light from the ocean surface or the underwater target is collected onto a slit in front of the streak tube photocathode by a conventional lens, and the time (range) is resolved by an electrostatic sweep within the streak tube, thus generating a 2-D range-azimuth image on each laser pulse [5,6], as shown in Fig. 2.…”
