Measurement of angle encoder disk surface parameters

Abstract

This research covers a novel approach to non-contact angle encoder disk roughness measurements while using the proposed system attached to the rotary table with an implemented reference angle encoder. Noncontact surface measurement methods are analyzed in the paper. The proposed non-contact surface roughness measurement technique involves the use of a conventional optical disc laser reading system as a cost saving solution. Assets and drawbacks as well as detailed analysis of the measurement procedure are given in the paper. The structure of the device is presented within this article together experimental results.
