Influence of Interference Deviation on Four-Beam Interference with Circular Polarization
The interference intensity distribution of four-beam interference with right-hand circular polarization is theoretically studied and simulated with MATLAB. The impact of incident angle on the intensity distribution of interference is studied. The results show that there is a uniform two-dimensional periodic intensity distribution when four beams show symmetrical distribution. The peak intensity appears at the intersection of three lines with the slopes of S1=+1, S2=¥, S3=-1, respectively. And there are certain periods dx=dy=λ/sin θ in the x and y directions. When incidence angle θ changes, the period of the pattern changes accordingly but not the symmetricity of pattern. However, when the incident angle or azimuthal angle (θ1,α1) changes, both the slopes Sl(l=1,2) and periods dxl,dyl(l=1,2,3) change.
