Space Variant PSF - Deconvolution of Wide-Field Astronomical Images

Original language description

The properties of UWFC (Ultra Wide-Field Camera) astronomical systems along with specific visual data in astronomical images contribute to complicated evaluation of the acquired image data. These systems contain many different kinds of optical aberrations which have a negatively effect on image quality and imaging system transfer characteristics, and reduce the precision of astronomical measurement. Models of optical aberrations serve as suitable tool for estimating and fitting the wavefront aberrationerror of a real optical system. Real data from the BOOTES (Burst Observer and Optical Transient Exploring System) experiment are used for our simulations. Problems related to UWFC imaging systems, especially a restoration method in the presence of spacevariant PSF are described in this paper. Models of the space invariant and partially space variant optical system have been implemented in MATLAB. The "brute force" method has been used for restoration of the testing images. T
