Paper Abstract

One of the major limitations of intensity interferometry both in space and time domain is that only the linearly filtered signals could be registered in photon-counting mode. However, this restriction can be removed by a prior processing of the registered signal in a simple way before image formation from the field correlation function. This is a typical example of ill-posed inverse problems for non- symmetric transforms. We investigate the implementation of eigen function method to the problem of correlation function restoration from the photocurrent data. The effectiveness of the restoration procedure for the typical examples of astronomic images is investigated by computer simulation, both for symmetric and non-symmetric objects with phase restoration by the application of incoherent reference source.
