Intensity Interferometry Image Recovery
This software extends the well-known error-reduction Gerchberg-Saxton method to imaging of dark objects, assuming that such an object partially shadows a well-characterized thermal light source, while the shadow cannot be used for inferring the object’s shape. These assumptions are reasonable for a wide...
