Holographic Polymer-Dispersed Liquid Crystals: Materials, Formation, and Applications

Figure 74

Diffraction pattern of an H-PDLC at a wavelength of λ = 1.96 nm. Diffraction up to the ± second order is visible (bottom). The data points result from summing up the box counts of 30 pixels along the y-direction around the centers of diffraction spots, so that the second-order peaks are clearly visible (top) [144].
