FOC Image Restoration Using Calculated PSFs on Parallel Architectures

Raadhakrishnan Poovendran John E. Dorband and Jan M. Hollis


We describe our image restoration efforts which use an analytical model of the point spread function (PSF) of the Hubble Space Telescope Faint Object Camera (FOC). Our approach is based on the Zernike polynomial modeling of the wave front phase using two phase retrieval algorithms. The difficulties involved in modeling the PSF and validating our approach are illustrated using actual FOC and simulated data which have been processed on a massively parallel computer.
