Thermal atomic layer deposited Al2 O3 thin films were applied at the front and rear sides of PERC-type C-Si solar cells.At the front side,A12 03/SiNχ as a double-layer antireflection coating reduced t
To the question of particle images segmentation with uneven illumination background,a novel method is proposed based on homomorphic filtering,Top-Hat transformation and watershed algorithm in this pap
The application of polymeric thin film planar optical waveguide based on attenuated total reflection (ATR) and thermo-optic effect as temperature sensor is demonstrated in this paper and the factors i
Introducing the Finite difference time domain method and perfect match layer absorbing boundary condition,the electro-tunable localized modes in two dimensional nematic-liquid-crystal photonic crystal
In micro optical electro mechanical systems,the air thickness of a Fabry-Perot cavity is about one wavelength.Therefore,the interference series is less and the reflection phases of the reflectors have
Aimed at the complexity of the traffic natural scene,this paper put forward a kind of triangle traffic sign detection method in the basis of Radon transform.the process of detection consists of three
An algorithm based on the scalar Extended Nijboer-Zernike (ENZ) theory is proposed for phase retrieval through single defocused intensity pattern.This algorithm draws on the generalized inverse matrix
