Design of high speed camera system with area-CCD KAI-0340DM

A camera system was designed by using conventional CCDs and several problems in a high-speed mode were saved.After introducing to the working principle of a interline array CCD KAI-0340DM,a highly integrated CCD signal processor was used to produce the high-speed timing signals.By improving the heat conduction efficiency between chip and board,the heat conduction area was enlarged so that temperature rising was reduced.A high-speed op-amp self-oscillation model was established,and the self-oscillation was overcome.Furthermore,the difficulty of data processing was reduced by the serial to parallel conversion.Finally,data was transmitted through Camera Link Interface,and output data were asynchronous depressed in frequence by compressing the blanking interval.The results show that the temperature has only gone up 5.2℃ when the camera system works;its signal to noise ratio is greater than 40 dB,and dynamic range is not less than 60 dB.The camera can work under the four resolutions.When the camera's resolution is 640×480,it can work in the Time Delay Integral(TDI)mode.When it is 228×164,frame frequency is 1 000 frame/s,it can meet the camera's basic application requirements.
