IRFPA No-uniformity Correction Using the DSP Image Processing System

Compared to single element detector infrared system, the most difficult problem associated with the IR focal plane array is spatial photo response no-uniformity. Although the uniformity of area detector’s arrays has been improved greatly, it is crucial limited performance for a staring IR system. The no-uniformity correction with applicability and real time is a key technology in the application of IRFPA. According to the theory of tow-point correction, a new no-uniformity correction method of IRFPA is carried out by using the DSP image processing system. Experimental results demonstrate that this method can effectively be used in real time infrared image processing.
