Abstract

Error calculation introduced by a spherical reflector form to the piston linear shifts measurement in the valve is considered in this paper. Error analysis is made according to the error dependence from the reflector radius. This error is established to be equal to 0,15mm and influences sufficiently the shift measuring results. Software-based error compensation method is suggested.
