Integrating Cube Scattering Detector

Abstract

The construction, calibration, and use of an integrating cube scattering detector used to measure scattering losses in optical fibers is described. The detector consists of six 1-cm sq silicon solar cells, each sensitive surface of which comprises one interior surface of a cube 1 cm on edge. Small holes in the center of two opposite faces of the cube permit the optical fiber to pass through the detector so that all the scattered light falls on a photosensitive surface.
