摘　　要：在机载激光探测海底地貌系统中，窄带干涉滤光片与ＹＡＧ调Ｑ倍频激光器中心波长的匹配非常重要。介绍了一种滤波器与中心波长匹配的方法。利用这种方法，得到了机载激光测深的实验结果。In a lidar receiver system,the optical interference filters are often used to eliminate the background signal.It is very important for the narrow band interference filter to match with the central wavelength of the Q switch double frequency laser,especially for the airborne laser bathymetrical system.In our experimental system,the interference filter is placed in emitting optical path.The intensity on output light is the integration of the product of the spectrum function of the filter and the emitting spectrum function of the laser.Adjusting the temperature of the filter,the central frequency of the filter can be moved to match the laser frequency,and to get maximum output signal.Based on the principle,the interference filter with central wavelength adjusting can be used in lidar receiver system to obtain the optimum receiving signal.
