During the development of the research and the manufacture technical, the Infrared thermal imaging systems has
developments advance rapidly. And its applied field has going deep into the space technology, industry, agriculture,
medical, traffic and other fields from the national defense and military appliance. Especially in the application of
the military, it has come into being a specialty IR System Engineering field. But in many important applications,
the lens calibre of the IR thermal imaging systems often be made very large to advance the SNR of the systems.
This increased the weight and the research cost of the whole system very much. Many research indicated that the
main factor to affect the image quality of the IR systems is the fixed pattern noise (FPN) or spatial non-uniformity
under the actual technical and manufacture level. If we using the effective dynamic self-adaptive non-uniformity
correction algorithms for the IR system, and use the image enhancement technology simultaneity. We can advance
the imaging quality greatly. With this plan, the correction image we got with large F number can receive the level
that uncorrected image with 1 or 2 smaller F number. It means the lens calibre of the system will be reduced
effectively. And the weight, the cubage and the research cost of the system will be reduced greatly. It will have
most important value in the applied of the actual engineering.
