SEMIAUTOMATIC SURFACE REFLECTANCE MEASUREMENT FOR MONITORING OF MATERIAL WEATHERING

V. Kocour, J. Valach

Abstract

We present a device for measurement of surface reflectance in dependence on incidence angle and reflectance angle. This measurement enables us to quantitatively determine how much the surface is glossy or matt. The device is programmable, which enables us to choose non-equidistant steps of angles, and study special situations more in detail. It can be used for monitoring of material weathering or other types of degradation as weathering usually causes that the surface becomes more matt.
