WitrynaThe present invention describes a liquid crystal composite tuneable device for fast polarisation-independent modulation of an incident light beam comprising: (a) two supporting and functional panels, at least one of them coated with a transparent conductive electrode layer and with optionally at least one additional layer selected … WitrynaThe class liyphilic.lib.order_parameter.SCC calculates the coarse-grained order parameter, as defined in Seo et al. (2024) . The coarse-grained order parameter, S C C, is defined as: S C C = 3 cos 2 θ − 1 2. where θ is the angle between the membrane normal and the vector connecting two consecutive tail beads.

Witryna11 sty 2012 · Polarization properties of first diffraction orders have been investigated as a function of the angle between the laser linear polarization and the grating direction. We propose to use two 1D gratings to create a 2D electrically controllable diffraction pattern, suitable for application in 3D optical devices. Witryna15 kwi 2024 · Two photoalignment-based methods to achieve orientational control of optical diffractions by cholesteric liquid crystal (CLC) fingerprint gratings are proposed and demonstrated. A trace of methyl red in the CLC host can effectively induce surface alignment upon linearly polarized green exposure and enable optically rewritable … program lefthand
