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. A waveplate or retarder is an optical device that alters the polarization state of a light wave travelling through it. Two common types of waveplates are the half-wave plate, which shifts the polarization direction of linearly polarized light, and the quarter-wave plate, which converts linearly polarized light into circularly polarized light and vice versa. A quarter-wave plate can be used to produce elli… fi sci games boardWebThe optical resting point of a polarimetric sensor is normally reached by using a fixed retarder plate. It is shown that this retarder plate can be omitted by using 90° prisms of selected glass materials.
