Abstract

During two color sensor fusion it is found that an electric time delay and integration (TDI) circuit can be replaced by an equivalent optical TDI method. This contains a dichroic mirror to separate dual wavebands into two image focal planes with a two-dimensional image translation between the image focal planes. The experimental result shows that performance of the fusion sensor is improved with an increased video signal to noise ratio and a lower minimum resolvable temperature difference. It can also provide a real time (30 frames) single enhanced dual band thermal image.
