摘　　要：采用MI-MV13和LUPA-1300-2两种不同厂家型号的高速CMOS图像传感器,设计了分辨率为1 280×1 024的300～500 frame/s高速数字工业相机,并在实验室条件下对设计相机进行了关键性能指标对比测试,得到了光谱响应及量子效率、增益、动态范围、暗电流、读出噪声、光电响应非均匀性等测试结果。测试分析显示,LUPA-1300-2的峰值量子效率为50%,比MI-MV13的峰值量子效率高12%,与厂家的参考指标基本一致。测试结果证明:该测试方法正确,对两种高速CMOS图像传感器的关键性能指标的测试客观可信,所设计的高速CMOS摄像机的性能基本满足高帧频摄像的要求。Two kinds of high-speed industrial digital cameras with a resolution of 1 280×1 024 and a high frame rate of 300-500 frame/s were designed based on two different models of high frame rate CMOS imaging sensors from two different CMOS sensor manufacturers.The CMOS image sensors are MI-MV13 and LUPA 1300-2.Some experiments of imaging performance evaluation by a laboratorial test were presented.Spectral response and quantum efficiency（QE）,gain,photoelectric conversion nonlinearity,dark-current,readout noise,full well electron quantity,dynamic range,etc.were tested and analyzed.Experimental results show that the LUPA 1300-2 is superior to MI-MV13 at quantum efficiency testing,and their peak value QEs are 50% and 12%,respectively,which is basically the same as the reference data of manufacturers.The test results prove that proposed test method is correct and the evalution for two high-speed CMOS image sensors is objective and credible.The high-speed CMOS cameras designed can satisfy the system performance requirements for a high-frame rate.
