Abstract

We have developed a SWIR (Short Wavelength Infrared) optical system for surveillance. The focal length of the optical system was 300 mm for a 640x512 pixel detector. The spatial resolution of the optical system has been designed less than 0.05 mrad. We have measured the spatial resolution to verify the optical performance. Also, we have observed a 2- cycle target at 3 km distance when the visibility was 1.7 km in the field test. We have proved to be able to get the image of a target by using our optical system with a SWIR detector in 1.5 times longer distance than the visibility range.
