Holographic Polymer-Dispersed Liquid Crystals: Materials, Formation, and Applications
Figure 3
Field dependence of transmission curve (squares), first-order diffraction curve
(circles), and total transmission curve (triangles) for (a) a POLICRYPS grating,
(b) a PDLC grating. The insets show typical (a) POLICRYPS, (b) PDLC grating
morphology with the same period, observed under a polarizing optical microscope
[18].
