Abstract

To enhance the performance of multispectral imaging, double-filtering method is applied, the double-filtering method that improves the spectral resolution and intrinsic sidelobes for the spectral domain analysis systems is described. Double filtering is realized by two kind specified AOTFs which are placed fore-and-after. The two AOTFs were designed especially. By changing the RF power the performance of the system can be enhanced.
