The construction features of autocollimation systems for measurement the large-sized and extended objects deformations at industry, power and scientific instrument making are considered. The conditions of increase of a distance of measurement are analyzed in comparison with the serial autocollimation devices. The error of measurement by the restriction of a working beam is investigated. The structure of algorithm for reduces the systematic error of the measurement which based on received analytical expression of function of an error is determined.

Keywords:autocollimator, vignetting, vignetting error, computer modelling, algorithm for reduce error
