Spectrophotopolarimeter based on multiple reflections in a coated dielectric slab

Dynamic acousto-optic photopolarimeter/spectrophotopolarimeter

“…Since at least four components are needed for complete polarimetry [16][17][18][19][20][21] and spectropolarimetry, 22,23 we select an AOD that operates in the Raman-Nath regime, where diffraction appears as a large number of diffracted orders. The grating is accurately described by the ''thin grating'' equation.…”

Merged vector gratings recorded in a photocrosslinkable polymer liquid crystal film for polarimetry

“…To solve these problems, Azzam proposed photopolarimeters that consist only of several photodetectors. 5,6 Vector diffraction gratings, which are formed by periodic distributions of optical anisotropy, are also of interest for polarimetry applications. [7][8][9][10][11][12][13][14][15] Vector gratings are easily fabricated by polarization holographic recording in photoreactive media, such as azopolymer films, and the diffraction properties of the gratings depend on the polarization state and wavelength of the incident light.…”

Tilted parallel dielectric slab as a multilevel attenuator for incident p- or s-polarized light

“…First-order blooming leads to a set of discrete attenuation levels that depend only on the number of internal reflections inside the slab but that are independent of the slab refractive index, incident (p or s) linear polarization, or the presence of identical transparent surface layers at the front and back sides of the slab. Tilted dielectric slabs are also key elements of divisionof-amplitude photopolarimeters that are used for partial or complete measurement of the state of polarization of light [11][12][13].…”
