Comparator With Optical Encoder System for the Calibration of Leveling Staffs

CODEN: JTEVAB

Abstract

Geometric leveling is the most precise and universal method used to determine heights. In order to achieve the greatest possible accuracy, the method demands a calibrated leveling staff, which requires an appropriate calibration facility. The encoded shape of the leveling staff demands the rebuilding of comparators designed for calibrating classical leveling staffs. The comparator MSGL001 at the Faculty of Civil and Geodetic Engineering in Ljubljana is based on an optical encoder system that is an original solution of snapshot positioning. The aim of this paper is to present the rebuilt comparator and the details of its testing.
