Based on the electro-optic effect the optical axis of each domain is alternately aligned at the angles of +h and h with respect to the plane of polarization of the input light. For such kind filter, each domain serves as a half-wave plate with respect to
WebThis invention provides a multipass Solc filter which utilizes liquid crystal variable retarders to provide high resolution and tunability. The Solc polarization-interference effects are used synergistically with the Fabry-Perot cavity resonances. The cavity comprises a central retarder, two quarter wave plates, and an optional isotropic spacer. WebA half-wave plate rotates 45-degree-polarization to -45-degree, and vice versa. R. Clark Jones (1916 - 2004) The orientation of a wave plate ... 3 = the excess in intensity of light transmitted by a RCP filter over light transmitted by a LCP filter What we mean when we say ‘unpolarized light’:
WebThis geometry reduces by half the number of required retarders, ensures the same spectral retardance function in pairs of retarders, and helps to make more compact filters. The key element is a quarter-wave Fresnel rhomb located in between the set of retarders and a mirror. Two cases are considered: the first Solc filter uses multiple-order WebDownload scientific diagram (Color online) Folded Solc filter schematic diagram. m couples of half-wave plates are held in two crossed polarizers.
