High Precision Position Measurement Method for Laguerre-Gaussian Beams Using a Quadrant Detector
In this paper, we propose a new method to improve the position measurement accuracy for Laguerre-Gaussian beams on a quadrant detector (QD). First, the error effects of the detector diameter and the gap size are taken into account, and the position error compensation factor is introduced into the co...
