Abstract

In this work we present the optical design of an instrument for measuring the scattering of light by a 2D rough surface in the visible between 550nm and 830nm. An elliptical mirror is used to collect the light scattered by a 2D-surface. The 2D-surface is placed at the first focus of the ellipse. A relay is placed at the second focus of the ellipse to collect the light scattered by the surface in each direction, that is, parallel rays leaving the illuminated 2D surface at an arbitrary angle are brought to a point at the focal plane of the relay. The light is detected by a CCD camera. To cover 180 degrees field of view it is necessary to move the CCD linearly in two directions in the focal plane.
