Operating principle of laser beam-riding guidance was set forth. Based on the principle of spatial frequency-encoding experimental results demonstrated that the receiver can receive correctly the encoded signal and can decode the signal an optimum laser encoding mode was designed measurement for the missdistance is feasible and all the performance parameters satisfy the demand. (2012) Trans Tech Publications which can transfer continuous laser into pulse laser that represents different position information. Then the mathematic model of deviation from target is built Switzerland. a modified encoding pattern was presented which is composed of two light paths crossed 90. Azimuth information of target is given in orthogonal coordinate system and deviation from target is linearity. As well as characteristic distribution of spatial laser field is analyzed. Corresponding decoding mode was presented by testing in 2 kilometers outdoor

To improve the fidelity of nanostructures in transfer process a composite stamp with reasonable hardness distribution in 184 PDMS used to nanoimprint was studied. The stamp is composed of a stiff 184 PDMS structured layer and a soft 184 PDMS supporter layer. We studied the relationship between the hardness of the 184 PDMS and the proportion of each component in 184 PDMS. The appropriate components proportions of prepolymer and curing agent corresponding to the different region of the composite stamp were presented. The fabrication method of the stamp is also presented. Corresponding experiments were carried out by using this stamp. Kinds of nanostructures were transferred in one inch diameter area with good fidelity. The feature sizes of the structures were less than 100 nm. 2012 IEEE.

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.

A color transfer method is presented to give fused multiband nighttime imagery a natural daytime color appearance in a simple and efficient way. Instead of using the traditional nonlinear l space the proposed method transfers the color distribution of the target image (daylight color image) to the source image (fused multiband nighttime imagery) in the linear YCBCR color space. The YCBCR transformation is simpler and more suitable for image fusion compared to the l conversion. The YCBCR transformation can be extended into a general formalism. And the paper mathematically proves that for color transfer using color spaces conforming to this general YC BCR space framework can produce same recoloring results as using the YCBCR space. Experimental results demonstrate that the YCBCR based color transfer method works surprisingly well for transferring natural color characteristics of daylight color images to false color fused multiband nighttime imagery and moreover can also be successfully applied to recoloring a variety of color images. 2010 SPIE.

We present a color transfer method which is designed to give fused multiband nighttime imagery a natural daytime color appearance in a simple and efficient way. Instead of using traditional nonlinear la space the proposed method transfers the color distribution of the target image (daylight color image) to the source image (fused multiband nighttime imagery) in a linear color space named ICBCR. The ICBCR transformation is simpler than the la conversion moreover the IC BCR space is easily extended to image fusion. Our experiments on infrared and visual images show that the ICBC R based color transfer method works surprisingly well for transferring natural color characteristics of daylight color images to false color fused nighttime imagery. 2009 IEEE.
