Achromatic polarization switch using a film-compensated twisted nematic liquid crystal cell
نویسندگان
چکیده
A broadband polarization switch consisting of an active twisted nematic liquid crystal cell and two passive uniaxial compensation films is analysed. The conjugate gradient method was used for optimizing the device parameters. Simulation results indicate that the polarization switch exhibits a broad bandwidth and high contrast ratio. The manufacturing tolerances on cell gap, twist angle and compensation films thickness are reasonably large.

Achromatic Linear Polarization Switch for Visible and Near Infrared Radiation Based on Dual-Frequency Twisted Nematic Cell
The switchable polarization rotators are of prime importance in many modern optical applications, such as displays, spatial light modulators, and beam deflectors. Such a rotator can be designed with a half-wave electrically controlled nematic cell with antiparallel alignment at the two boundary plates. However, this rotator can operate only in a narrow spectral band where the half-wave conditio...
متن کاملP-156: Transflective Double Cell TN Liquid Crystal Display
Double cell Twisted Nematic (DTN) liquid crystal display is optimized for transflective liquid crystal displays, using MOUSE-LCD software. Two configurations of such DTN-LCD were simulated using a double and a single cell gap approach. DTN-LCD exhibits a high contrast ratio, wide viewing angles and achromatic (black/white) switching in both the transmissive mode and reflective mode. It also pos...

We show how a tightly focused laser beam can serve as a tool to image complex patterns of the director using the technique of fluorescence confocal polarizing microscopy (FCPM). We expand the capabilities of FCPM into the domain of real-time scanning in order to study the dynamic processes at the time scale of about 1ms. In this approach which we call Fast FCPM, confocal imaging is performed us...
متن کاملEfficient polarization converter for projection displays.
In the waveguiding limit, a twisted nematic liquid crystal cell behaves as an achromatic polarization rotator. We propose and demonstrate the application of such a polarization rotator to convert unpolarized light into linearly polarized light with almost 100% efficiency. This polarization converter has a 2:1 aspect ratio, which is close to the 16:9 ratio for modern televisions. It can be used ...
متن کاملBeam steering for virtual/augmented reality displays with a cycloidal diffractive waveplate.
We proposed a switchable beam steering device with cycloidal diffractive waveplate (CDW) for eye tracking in a virtual reality (VR) or augmented reality (AR) display system. Such a CDW diffracts the incident circularly polarized light to the first order with over 95% efficiency. To convert the input linearly polarized light to right-handed or left-handed circular polarization, we developed a br...
