Paper Abstract

In this paper, the author reports a photoelastic modulator based linear birefringence measurement system (BMS) using a near IR laser . This instrument determines both the magnitude and angle of a birefringent sample without rotating the sample. It records birefringence images by scanning a sample that is mounted on a computer-controlled X-Y translation stage. The accuracy, repeatability and other key performance test for the NIR-BMS are provided in this report. Selected samples, including silicon optical components, a silicon wafer and waveplates commonly used at visible wavelengths, are studied using the NIR-BMS.
