Paper Abstract

In this paper an integrated scanning laser sensor system with large working distance for 3-D free form measurements is described. The sensor system consists of one diode laser light source and four position sensitive device (PSD) detectors. By the Lambertin model for diffusing surface, the fundamental analysis is performed. The working distance is 150 mm - 200 mm and measuring range is 80 mm. Therefore, the scanning measurement can be realized almost without Z axial tracing. Meanwhile the surface normal direction that is the inclination angles along the X axial and Y axial can be calculated at the same time. According to the inclination data, the measurement error can be compensated by verification database. Computer simulation and preliminary experimental results are also given in this paper.
