Paper Abstract

The principal aim of this paper is to present a general view of the special optical systems used for acquiring of the astronomical image data, which are commonly called WFC or UWFC (Ultra Wide Field Camera), and of their transfer characteristics. UWFC image data analysis is very difficult. Images obtained from UWFC systems are distorted by many various optical aberrations. The influence of optical aberrations increases towards margins of the field of view. These aberrations distort the point spread function of the optical system and rapidly cut the accuracy of measurements. UWFC systems frequently have so called spatially variant properties. This paper deals with simulation and modeling of the UWFC optical systems used in astronomy and their transfer characteristics.
