Paper Abstract

This paper reports on (1) the development of a fully optoelectronic BRDF sensor, and (2) first experimental results obtained with an automated setup consisting of the sensor, stages for specimen scanning, as well as PC hard- and software for the control of the setup and the evaluation of data. Main points covered are the construction of the sensor head, problems with the alignment of the hundreds of fibers needed, how to reach the necessary high dynamic range of the CCD camera employed, and the control of the laser diode.
