The aim of this thesis is to provide the French Metrology with a reference instrument that can be used for measuring the appearance of objects. Several physical properties of object appearance are used not only to identify the object itself but also determine its quality. These include color, gloss, texture and translucency. This work describes the design, characterization and the implementation of an instrument that has been built particularly to measure the bidirectional reflectance distribution function (BRDF) of planar surfaces. BRDF is a physical quantity that enables measuring the surface color and gloss. Accordingly it is important to ensure accurate and traceable measurements of such a quantity in order for a comprehensive understan...
