Abstract

We have developed two range gating laser imaging systems, which base on modulated gain method and centroid algorithm respectively. The system based on centroid algorithm uses a pulse laser as transmitter and CCD with image intensifier, through delaying gated receiver repetitiously to acquire a series of 2D time-slicing image to restore the three-dimensional rang image. The imaging system based on modulated gain mainly adopts the same pulse laser is used and CCD with image intensifier with constant and modulated gain over time, which can capture two different intensity images of echo pulse respectively in order to restore the three-dimensional range image. We conduct a series of experiments with the tow system, and the results are consistent with the actual practical ones. By comparing result of laser imaging based on the two systems, we summarize the different strength and weaknesses, requirements, and challenges to lay a solid foundation for later experiments.
