Paper Abstract

This paper presents a surface shape measurement system based on laser deflectometry. System’s design aims at application in documentation of objects of cultural heritage. The system is composed of a semiconductor laser, a CCD camera and imaging optics. The principle of measurement involves ray tracing of the laser beam calculated from two positions of the detector along the optical axis to determine the angle of inclination of the measured surface. The object is scanned with the designed system and resulting surface normal vectors are integrated to form the output surface. Exemplary measurement results are presented and discussed.
