Abstract

This paper reviews the design of a rather unique portable scatterometer. The instrument consists of a measurement head connected by cable to a microprocessor based controller. Several different measurement heads can be used with the same controller. One measurement head is a hand held unit designed initially to measure rain erosion on aircraft sensor windows. The controller stores the scatter by aircraft tail numbers and downloads them later to a PC. A second head, a little larger than a shoe box, is designed to take either reflective or transmissive measurements from optics. The objective is to make inexpensive, fast, accurate BSDF measurements available in a variety of situations where location, or expense, has prevented it in the past. The paper gives specifications for the two heads and compares measurements to those taken on a TMA CAS1.
