Wavefront detection of extended-beacon based on phase-space optics

摘要

The extended beacon belongs to partially coherent light field, and Phase space optics is an effective tool for analyzing such light field, especially in calculating the phase of multi-angle and multi-layer. Due to the lack of directly detection means, the research of this theory is crippled a long time, in this paper an optical structure to obtain the spectrogram which is a kind of phase space distribution has been presented, while the resolution problem and an improved method for possible has been discussed too, and two new methods to get high quality astronomical Image are appearing with such algorithm.
