Polarizer

 

a device for obtaining completely or partially polarized light from light with arbitrary polarization characteristics. It is the simplest polarizing device and one of the main elements in more complex devices. Linear polarizers, which produce plane-polarized light, take the form of optically anisotropic polarizing prisms, polarizing sheets, and optical piles of isotropic plates transparent in a given region of the spectrum. A combination of a linear polarizer with quarter-wave plates is used to obtain circularly polarized light. Any polarizer can also be used as an analyzer of polarized radiation.

"The move is to have an integrated polarizer production system targeting display companies in southern China," the official from the company said.
where P([theta]) is the Muller matrix of polarizer; [theta] is the direction of the transmit axis and the subscript numbers of [theta] are the polarizer and analyzer, respectively; D(d) is the Muller matrix of the depolarizer (including the polarizer and color filter); d is the degree of depolarization.
This paper mainly focuses on the design principle, measurement, and contrast method towards the dual-channel 3D QON system between FSS and polarizer. This dual-layer mirror structure can transmit 324 GHz channel on the top layer and reflect the 183 GHz to the bottom layer.
For the polarizer is an orthotropic structure, the reflected and transmitted waves would consist of both x- and y-polarized components.

1) consists in two identical polarizers (P1 and P2) having the cell (C) containing the HPC polymer solution (as an optical active layer) between them, in the measure beam, as well as two identical polarizers placed in the compensatory beam (P3 and P4).
"Conventional polarizers operate by rejecting undesired polarization, which limits their transmission efficiency to much less than 50 percent when illuminated by unpolarized light," the researchers wrote.

COSMOSHINE (SRF type) is a new kind of film made possible by a contrarian concept that overthrows existing common knowledge that held that materials, other than polarizer materials used thus far in LCDs, must be isotropic.
Ultimately, by using an appropriate arrangement of materials in layers, we can approach our desire to make low-pass & polarizer filters [13-15].
