Abstract

The basic technologies of designing dual-band imaging system (3 - 5 micrometers , 8 - 14 micrometers ) can be researched in this paper. We study the ratio of the dual-band radiating energy in the different regions of temperature. The relation between S/N ratio and NETD of a dual-band imaging system is discussed and compared with a single band in detail. The S/N and NETD of a dual-band imaging system is 5 times over that of a single imaging system. By calculating and analyzing the imaging characteristic and the dual-band (3 - 5 micrometers , 8 - 14 micrometers ) detectors with the same focus plane and size, the fusion technology in level of pixel is obtained and realized using main-self fusion structure, which the processing and complexity of a dual-band can be reduced.
