Abstract

A polarimeter system has been developed to investigate the reflected light of very rough non-specular surfaces. One special application is the polarimetric analysis of road surfaces to find features for the classifications relating to type and surface condition. The reflected light of such a surface varies very much depending on the inhomogeneous surface structures. The aim was to build a measurement system which is relatively insensitive to the positioning of the surface sample, is easy to calibrate and offers a high scanning rate. These demands lead us to a polarimeter setup using a combination of a four-detector-polarimeter and a retarder-polarimeter with liquid-crystal cells as retarding elements. With the help of this laboratory system it is possible to find all polarization depended features. In a further step the setup will be simplified to measure only selected values but with higher speed. The software of the system allows the complete control of the polarization generator and of both polarimeters including the calibration,the operation in different modes, the evaluation and graphical visualization of the measuring data.
