AbstractIn viewpoint of signal processing, we describe the principle of collimator-based Fourier-transform imaging, from verifying Fourier-transform function of collimator to presenting theoretical model of dirty image. This gives us a guideline in designing collimator imager, that is configuring the subcollimators properly to improve the quality of the dirty image. Here we optimize the arrangement of the subcollimators of YOHKOH Hard X-ray Telescope (HXT) to get the Point Spread Function of sidelobes as small as possible and simulate that with MATLAB.
