Abstract

A theory of realizing dual band thermal images by pyroelectric FPA detector with 4 states of chopper modulation is proposed. The rules governing the variations of signal responses to temperature rise from the scenery incident emission under 4 states of chopper modulation and successive signal processing in the detector are established. Analysis of the digital analog shows that the double bands (3 to approximately 5 μm and 8 to approximately 14 μm) information of the scenery emission may be totally or partially separated. By this technology, a light, low cost, double band thermal imaging system with single detector could be realized.
