Holographic Polymer-Dispersed Liquid Crystals: Materials, Formation, and Applications
Figure 77
Diffraction efficiency as a function of incident angle for (a) - and (b) -polarized light.
The data is for an H-PDLC transmission grating
with Λ 0.5 μm
probed at 632.8 nm. The grating thickness is about 10 μm. A fit to coupled-wave theory yields (a) = 0.054 (-polarization) and (b) = 0.019 (-polarization).
