Transmission of light through right-angle corners in hollow light guides
Abstract:
Transmission of light through the corners in hollow light guides is compared for a new type of corner that is based on a laser-cut light-deflecting panel and for a flat, 45°, mirror-type corner. Corner efficiency is defined, and an experimental method for the measurement of the corner efficiency versus the angular width of the input light is described. Measured corner efficiencies were found to be nearly independent of the angular width of the incident light for metallic hollow light guides, with the average efficiency of the laser-cut-panel corner (65%) lower than that of the mirror corner (80%).
