Computing imaging data using intensity correlation interferometry

摘要

A method includes receiving, at a computational station, photodetection data, originating at a source, encompassing a set of frequency channels and collected at a number of light gathering telescopes. The method also includes determining correlation between the received photodetection data in each frequency channel, and determining a time average of the correlation between the received photodetection data in the each frequency channel. Further, the method includes determining an average over the set of frequency channels to arrive at a mutual coherence magnitude for each pair of the number of light gathering telescopes, and computing imaging data of the source based on the determined mutual coherence magnitude and the correlation between the received photodetection data.

1. A method comprising:
receiving, at a computational station, photodetection data, originating at a source, encompassing a set of frequency channels and collected at a plurality of light gathering telescopes; determining, through the computational station, correlation between the received photodetection data in each frequency channel; determining, through the computational station, a time average of the correlation between the received photodetection data in the each frequency channel; determining, through the computational station, an average over the set of frequency channels to arrive at a mutual coherence magnitude for each pair of the plurality of light gathering telescopes; and determining, through the computational station, imaging data of the source based on applying a phase retrieval technique that computes the imaging data from the determined mutual coherence magnitude and the correlation between the received photodetection data.
