Investigation of accuracy characteristics of circular photodetector 'Multiscan'

摘要

This article is about the research of precision characteristics of a circular sensor "Multiscan". The research was conducted on installation which base was a goniometer GS-5. Such characteristics as nonlinearity, stability, error of reproducibility of results of measurements were investigated. A scheme for arranging the encoder on the basis of a circular photodetector "Multiscan" is proposed.
