Fig. 2: Polarization patterns of the polarization holographic light field that results from the interference of R1 and R2o and is independent on microwaves.
a R1 and R2o are orthogonally linearly polarized along x- and y-axes, respectively, with the same intensity. Points A–D are on the red circle whose plane is perpendicular to the line joining R1 and R2o. Points A and C are on the S2-axis. Points B and D are on the S3-axis. b R1 and R2o are elliptically polarized with the same intensity. Points B and D are on the S2-axis. Points A and C are in the middle of B and D. c R1 is RCP and R2o is LCP with an intensity ratio of 2:1. Points A and C are on the longitude passing through the S1-axis of the Poincaré sphere. Points B and D are in the middle of A and C. d R1 and R2o are ±45° linearly polarized, respectively, with an intensity ratio of 2:1. Points A and C are on the equator of the Poincaré sphere. Points B and D are in the middle of A and C. e Experimental validation of the simulated polarization pattern of c using a linear polarizer. Due to spatial polarization modulation within PHLF, the light intensity distribution captured by a CMOS camera varies with the rotation of the polarizer’s optical axis that is marked with a purple arrow.
