Organic-inorganic composite materials have great applications in integrated optics due to their good optical performance. In this study, GeO 2 -based organic-inorganic films doped with azobenzene were prepared by combining the solgel technique and spin-coating method. The waveguide properties including refractive index film thickness response of different germanium contents been investigated. results indicate that increases, but decreases as content increases. 0.2 mol exhibits best...
Abstract Curved liquid crystal display (LCD) suffers from an issue of uneven brightness among the vertical‐alignment LCD panels based on thin glass substrates. In this work, we investigated its origin through optical simulation and successfully realized uniform brilliance for 27‐inch curved panels. The revealed that dark areas bending sides panel originated reduced azimuth angle crystals (LC) next to ITO trunk. This could be resolved by decreasing pretilt LC color filter side. Through...
Noninvasive object imaging through strongly-scattering turbid layers has attracted the attention of many experts due to potential application in biomedical and bioscience. The traditional speckle correlation method with Gerchberg-Saxton (GS) algorithm is used restore a single-shot pattern. However, this suffers from problems convergence local minimums, iterations cannot determine direction, randomly assign initial value GS algorithm. Bispectrum analysis enables directional Fourier phase...
Curved liquid crystal displays (LCD) suffers from an issue of uneven brightness among the vertical‐alignment (VA) LCD panels based on thin glass substrates. In this work, we investigared its origin through optical simulation and successfully realized uniform brilliance for 27‐inch curved panels. The revealed that dark areas bending sides panel originated reduced azimuth angle crystals (LC) next to ITO trunk. This could be resolved by decreasing pretilt LC color filter (CF) side. Through...
