Abstract

The goal of this project was to build a device capable of measuring both the specular reflectivity of black materials, as well as the Lambertian reflectivity of white materials over their full range of incident and observed angles, respectively. The MADLaSR (Multi-Angle Detection of Lambertian and Specular Reflectivity) is a device designed for specular reflectivity testing in the range of 10° < θ < 160° and for Lambertian reflectivity testing in the range of 10° < θ < 85°. The data collected from this device may be used to influence the design of optical systems, aerospace structures, or other devices in which maximum light control is a necessary consideration. This paper will discuss the design and functionality of the MADLaSR.
