Calibration of precision polygon/autocollimator measurement system

Abstract

Measuring system of polygon/autocollimator is considered the most accurate widely available means of angle measurement, therefore its accuracy researches are of high importance. In this paper we describe the experiments of both autocollimators and polygon calibration implementing the equipment of average accuracy. The calibration data analysis given allows determining the errors of equipment without implementation of high accuracy reference means of measurement. The results of calibration of both autocollimators and precision polygon are also given in the paper.
