Abstract
A novel method is described for sampling images formed with quasimonochromatic light at or near the diffraction limit of the primary imaging system. The high-resolution sampling method uses a binary phase grating placed in the primary image plane. The grating produces multiple images of the entrance pupil that can be spatially filtered to achieve a periodic amplitude modulation in the relayed image. It is shown that the modulation is insensitive to the degree of coherence in the image.
