基于OAM光束的旋转多普勒效应运动参数测量
Measurement of Rotational Doppler Effect Motion Parameters Based on OAM Beams
摘要
Abstract
The article elaborates on the latest research progress related to the rotational Doppler effect(RDE)technology associated with orbital angular momentum(OAM).The experiments employed OAM beams characterized by topological charges l=±2,±4,±6,achieving high-pre-cision measurements of rotational velocity and frequency with an error margin of merely 1.23%.The congruence between our experimental findings and theoretical forecasts attests to the accuracy and dependability of the RDE methodology.To address the perturbations induced by atmospheric turbulence on OAM beam propagation,we formulated a probabilistic model delineating the dis-crepancy in the orbital angular momentum quantum numbers between received and emitted pho-tons.Subsequently,the article engineered an experimental optical setup incorporating a random phase plate to emulate the perturbations of atmospheric turbulence.The experimental data corrob-orate the accuracy of the theoretical model,indicating that the probability distribution of quantum number differences for orbital angular momentum(OAM)beams in atmospheric transmission is in accordance with theoretical predictions.关键词
