Abstract

With the sustaining development of application requirements in infrared technology, modern infrared imaging system demands high frame rates, wide dynamic range, high spatial resolution and high sensitivity. Because it is impossible to integrate hundreds of pF capacitor in the limited area of detector pixel, the integration time of infrared staring imaging system will be restricted. Therefore, the underutilization of detector performance is unavoidable. Specially, long wave infrared detector must accommodate stronger infrared signal, and the integration capacitor is more easily saturated. For the sake of resolving the restriction of integration capacitor, an infrared image superframing technique based on high-speed digital transmission circuit is presented in this paper. Meanwhile, the mass raw data high-speed transmission from detector to imaging circuit is also capable via the proposed technique. With the usage of the technique, the signal to noise ratio (SNR) of infrared imaging system will be improved, and the dynamic range of infrared imaging system will be also extended. The theory analysis and results of simulation demonstrate that the proposed method is feasible and effective.
