| Abstract: | The weak signal processing in the technology of thermal imaging is studied in this paper to expand the application of the technology of thermal imaging which is to be applied to commercial areas besides the military purposes. The weak signal output of the SPRITE detector is amplified and buffered by the avilable AD797 as the core IC. Furthermore, the related parameters and several problems, which particular attentions should be paid to,in the design is given. |
