New Thermal Imager for Long Range Surveillance

摘要

The concept and design of a new thermal imager branded Attica M-ER is presented which isrndedicated to long range border surveillance applications. The camera makes use of a 1280×1024 pixelrnCMT or InSb detector being sensitive in the MWIR atmospheric window between 3 and 5 micron. Forrnhigh quality imaging with fields of view between 0.6° and 30° a 50× IR optical zoom lens is designedrncomprising 11 lenses. Five of the lenses are aspheric and one in addition with a diffractive surfacernstructure. Specially adapted image processing algorithms for homogenization, edge enhancement andrndynamic compression as well as automatic functions (focus, contrast, brightness, etc.) are completingrnthe package. Video clips of a first application and examples of image simulation are also presented.
