High Order Optical Aberrations Influence to Precision of Astronomical Image Data Processing

摘要

There are data evaluation of the astronomical optical systems and description of their transfer characteristics presented in this paper. The real data from the BOOTES (Burst Observer and Optical Transient Exploring Monitor) experiment and from double-station video observation of the meteors are analyzed. The BOOTES is a system for monitoring the optical transient of GRB (Gamma Ray Bursts). The main goal of the double-station video observation of the meteors is acquiring of meteors video records and their analysis. Precision of image data post-processing and analyzing, which is very important for these systems, decreases because of a lot of different kinds of optical aberrations and distortions. It proves itself at most on the frontier of the field of view (FOV). This paper includes the description of astronomical data analysis methods and their demos for different values of distortion. There is also a relation between high order aberrations influence and astrometry measurement precision discussed in this paper.
