Phase Techniques for Imaging and Recognition

摘要

Research is described on two aspects of phase manipulation in optic alprocessing. Phase diversity uses multiple observations of image, where the optical system is changed in a known fashion between observations. The images are processed to remove the effects of unknown phase degradations. We also study binary phase-only filtering and find that the binarization can be done in a phase-rotated space which gives rise to improved object recognition. One dimensional example of both techniques are given. (r.h.)
