A Low Cost, High-Performance Multi-Spectral Imager
Phone: (719) 599-7700
Multispectral imaging has become a valuable tool in tactical imaging scenarios due to the ability to expose camouflage, identify airborne toxins and fuel plumes, and the ability to provide night vision through the use of infrared imaging. Micro bolometer arrays work well in these situation by creating a single sensor which is sensitibe from the visible to long wave IR imaging regions. The microbolometer works well in an uncooled environment, eliminationg the need for cryogenics. Most of the problems with existing mirobolometer arrays is tied to the facr that the signal to be recovered consists of a constant bial current with an extremely small fluctuation riding on top of it. Sophisticated CMOS processing circuitry must be included at each pixel of the microbolometer array to sense this small signal. SMD proposes a new type of micrbolometer array which simultaneously increases sensitivity while decreasing fabrication complexity.
