Optics retarder

WebApr 1, 2024 · A useful approach is to build an optical system that is equivalent to a linear phase retarder/linear diattenuator, which has a fast axis/transmission axis that can be changed electrically. This can be achieved using an electro-optic device, such as an electro-optic modulator or liquid crystal variable retarder [6], [7]. WebAn imaging Stokes-vector polarimeter using liquid crystal variable retarders (LCVRs) has been built and calibrated. Operating in five bands from 450 to nm 700 nm, the polarimeter can be changed quickly between narrow (12°) and wide 160 ( ∼ 160 °) fields of view.
