Application Number: JP,2022-025984
Category (FI): G01J4/04@Z
Stage: PROBLEM TO BE SOLVED: To perform simultaneous measurement of left circularly polarized light and right circularly polarized light of which electric field vectors rotate in the opposite directions to each other with high sensitivity and accuracy in a simple configuration.SOLUTION: An optical measurement system includes an optical system for measuring circularly polarized light and a control system for controlling the optical system. The optical system simultaneously measures left circularly polarized light and right circularly polarized light in opposite directions to each other in two spatially separated optical paths. The control system corrects the measurement results of the left circularly polarized light and the right circularly polarized light by a correction function and outputs the measurement results. The correction function compensates for the characteristic variation between the two optical paths based on a reference value measured in the two optical paths using unpolarized light.SELECTED DRAWING: Figure 1 (Grant)
