Abstract

Two kinds of sensors were developed that can precisely measure a leaf's thickness. By an analysis of optic characteristics of the gauge head device, the actual transmission characteristic equation was established. The authors analyzed these precision instruments and carefully investigated the structural parameters related with principal error. Therefore, some schemes were proposed to reduce principal error and adjusted actual characteristic. This article also calculated the error resulting from contact deformation of the gauge head.
