Paper Abstract

High accuracy shift control of the large-size constructions (such as turbine or radio telescopes elements) is one of the tasks that could be solved by means of the optical-electronic autoreflection measurement system. The description of the system built on the autoreflection optical scheme with CCD-sensor, its design, accuracy characteristics and testing results are presented. The point image center determination algorithm with accuracy within 0.05 pixel as well as coordinate system conversion method and the results of theoretical estimate of total system's accuracy are also described. Influence analysis of optical components decenterings on the system's total error and sighting line displacement is also described. It is shown that decentering of focusing optical element is the primary impact. Precision characteristics were approved during the experiment; total error did not exceed 0.1 mm at a distance of 20 m.
