Symmetry detection of rotating patterns based on rotational Doppler effect of light
文献摘要：
We propose a method for detecting the symmetry of rotating patterns based on the rotational Doppler effect[RDE]of light.The basic mechanisms of the RDE are introduced,and the spiral harmonic distribution of rotating patterns is analyzed.By irradiating the rotating pattern using a superimposed optical vortex and analyzing the amplitude of the RDE signal,the spiral harmonic distribution of the pattern can be measured,and then its symmetry can be detected.We demonstrate this method experimentally by using patterns with different symmetries and shapes.As the method does not need to receive the scat-tered light completely and accurately,it promises potential application in detecting symmetrical rotating objects at a long distance.
