Pulsed laser/background light simulator

In this paper a pulsed laser/background simulator used for debugging and testing system performance of laser range finer (LRF) is introduced. This simulator is composed of a 1064nm- laser diode, an iodine tungsten lamp and its power supply, a collimating optics system, drive circuit, synchronal and delay circuit, simulating and computing code. This simulator can simulate the laser echo signal and the background radiation of a pulsed LRF when LRF ranges target with different distances and different characteristics under various atmosphere conditions.
