WebApr 13, 2024 · In this study, we theoretically and experimentally investigate the evolution properties of the CSD amplitude and phase of a PCLG vortex beam after it propagates through two cylindrical lenses with varying angles. Combining the above with self-referencing holography [ 33, 34 ], the CSD distribution of a PCLG vortex beam can be … WebInduced Circular Dichroism of Chiral Nematic Cellulose Films Catherine D.
