Abstract:
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.
