This paper proposes a new restoration method  only using the single image information  combining atmospheric physical model with fusion techniques to reduce the degradation of the image contrast in bad weather conditions caused by atmospheric aerosols  such as haze and fog. The basic idea of this method is to utilize physics-based model method instead of multisensors to generate a serial of virtual images  and then to fuse those virtual images into a high contrast image based on the wavelet fusion technique. In contrast to previous methods  our restoration technique is not only independent on predicted structure  distributions of scene reflectance  or detailed knowledge about the particular weather condition  but also adapt to the situation without a reference image or images with moving objects captured by a video camera. Experiments on different poorcontrast images demonstrate the availability of the proposed method in case of restoring the atmospherically blurred images. 2010 IEEE.

Aluminum is a typical active metal very easy to oxidize. An oxide surface layer of about 2-6nm quickly formed in air which adds difficulty to the optical constants determination. An ex-situ method is used to determine the optical constants of aluminum thin films. First  Second  Third  alumina (Al2O3) thin film is deposited by ion beam sputter deposition. The optical constants and thickness are determined by spectral ellipsoemtry (SE). The thickness is verified by grazing x-ray reflection (GXRR) fitting method  Al thin film with an Al2O3 cap layer on top is deposited. This cap layer is of the same deposition condition with the first step. By fitting the GXRR spectra  based on the acquired structure information  the structure information (the thickness of the aluminum and the cap layer  the ellipsometric spectra are fitted. The optical constants of the aluminum layer are extracted with the aid of the Drude model. Finally  surface roughness and the diffusion between Al-Al2O 3) is obtained  an induced transmission filter (ITF) is designed and deposited.

Optical interconnection is the key technique of high-speed optical information process and optical communication. A lot of approaches for optical interconnection have been proposed since Goodman in Stanford University firstly proposed the optical interconnection for very large scale integrated circuits technology. A dynamical addressing device for optical interconnection was designed and fabricated in this paper. This optical device is based on one-dimensional nonlinear photonic crystal made on the planar waveguide. The nonlinear materials ZnS and ZnSe  which have large nonlinear refractive index coefficients  were alternately deposited on the waveguide to form one-dimensional photonic crystal. The Bragg condition is changed when the input power of the control light increased due to the nonlinear characters of the materials  thus the reflective angle of the signal light can be changed with the input power change of the control light. In our experiment  when increasing the power density of control light from 0 to 2.60X105W/cm 2  the angle of the signal beam can be changed about 20. The interconnection characteristics were investigated in theory and in experiment. The testing data agree well with theoretical predictions. This kind of devices is promising to use in the all-optical interconnection  optical information processing and optical communication.
