Dual-beam-real-time polarimeter

摘要

A device for measuring the rotation of the plane of vibration of linearly polarized electromagnetic radiation includes a beam splitter that divides the radiation into beams following a measurement beam path and a reference beam path, and each of the beam paths are analyzed after interaction with a reference element and a sample to be measured. The beams impinge upon photosensitive sensors and the output signal from such sensors is processed to determine the characteristics of the sample that are desired to be analyzed.
