Application and test of two different high-speed digital CMOS image sensors

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.
