Studied the transient thermal transfer analysis method due to a kind of supersonic ellipsoidal dome  which is a conformal dome. Illuminated the principle of transient thermal transfer analysis. Accomplished the transient thermal analysis based on the model of ellipsoidal dome  and studied the influence about the different material and the different velocity. Considered three materials consist of MgF2  Al2O3  and ZnS  and meanwhile  the velocity was Mach2.5  and the time consists of 10s  20s and 60s. The temperature initial loads were from FLUENT thermal simulation. The thermal conduction analysis and the thermal convection analysis were finished in software ANSYS  in which the entire transient thermal analysis consists of modeling  meshing element  calculating and getting the results. The different temperature distributions based on varied time were gotten about the different materials. The results from analysis showed the temperature distribution of the structure of ellipsoidal dome  which could help the following coupled thermal-structure analysis. 2011 IEEE.

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.

In the latest 20 years  x-ray imaging technology has developed fast in order to meet the need of x-ray photo-etching  spatial exploration technology  high-energy physics  procedure diagnosis of inertial confinement fusion (ICF) et al. Since refractive index of materials in the x-ray region is lower than 1  and x-ray is strongly absorbed by materials  it is very difficult to image objects in the x-ray region. Conventional imaging methods are hardly suitable to x-ray range. In general  grazing reflective imaging and coding aperture imaging methods have been adopted more and more. In this paper  according to user's requirement  we have designed a non-coaxial grazing KBA microscope. The microscope consists of two sets of perpendicular spherical mirrors  each set includes two parallel mirrors. Taking it as an example  we have compiled an optical computing program for the non-coaxial grazing imaging systems so as to analyze and evaluate aberrations of KBA microscope. Thus it can help us to get an optimal comprehension of KBA x-ray imaging system. In the same time  the analytical results provide reliable foundation for evaluating imaging quality of KBA microscope.
