摘要
Abstract
To evaluate laser pointer ’s localization accuracy of moving objects, a laser spot measurement system is typically used to measure the spot of a 1.064 μm-wave-length laser on the tar-get.However,the maximum measuring distance of existing laser spot measurement systems is only 500 m,which needs to be substantially increased.This essay analyzes the constraints of laser spot dis-tance measurement,studies the methods for increasing the measuring distance of repetitive-frequency laser spot in field,designs a shutter optimal control strategy based on the use of a high-quantum-effi-ciency near-infrared camera which is able to precisely control the shutter exposure.A 99.9% laser spot admission rate is guaranteed,meanwhile the laser spot image SNR is increased about 8 times by con-trolling the camera exposure time.In field,the measuring distance of frequency-repetitive laser spot reaches 2 000 m,which meets the precision requirements for moving target measurement.关键词
