Research on infrared imaging system of UIRFPA based on virtual instrument

With the rapid development of Uncooled Infrared Focal Plane Array (UIRFPA), the infrared image technology is applied widely in many relative fields. So the infrared imaging system with high quality real-time image processing becomes more important. In this paper, a new way for the exploration of the infrared real-time imaging system is developed. The infrared imaging system is designed based on virtual instrument. A Non-Uniformity Correction (NUC) is applied by using two-point linear correction algorithm. Meanwhile, in order to enhance the contrast, the author preprocesses the image with the liner gray stretch on the premise of NUC. Through the test of UL 01011 320×240 and the analysis of the data by the imaging system, the results show that: the system can provide the real-time imaging, non-uniformity correction and gay stretch successfully. The infrared image is characterized by good uniformity and contrast.
