Abstract
For the two colour (3∼5um and 8∼12um) sensor fusion, an optical method can replace the electric time delay and integration (TDI) circuit. During the fusion process, there exits an optimal relative gain setting between the two preamplifiers of the sensors. The optical method can provide a real time (30 frames) single enhanced dual band thermal image with an improved signal to noise ratio and better system performance.
