Interferometry is a very important method in high accuracy measurement for optical system. This article briefly introduced the conception of interferometry and took a product of 4D Technology as an example to carry on the measurement. A large-scale optic-electrical Theodolite in assemblage was measured  and its primary mirror was 400mm in diameter. With the analysis of the results  some micro adjustments of the mechanical structure proceed  and it made the system perform better. The final results of the whole system is 1.061 in P-V value and 0.1136 in RMS value (=632.8nm)  this meets the demand of optical design and practical application. The result demonstrates that interferometry is a good way to be utilized and optimize in the procedure of assemble. (2013) Trans Tech Publications  Switzerland.

According to the focal depth and work environment of a space camera  a focusing mechanism is designed  which consists of precision screw ball transmission and linear bearing guidance and accuracy improving. The dynamic- strike- resistance  adaptability to temperature and vacuum are considered into the reliable design method. Furthermore  the linearity error  the structure stability and the mechanism work situation in high and low temperature are tested. The result is that the linearity error of the mechanism is less than 0.003 mm  and the sway error of vertical way and level way of the mirror is less than 20''. The linearity error of the mechanism and the sway error of the mirror remain unchanged after vibration test. The mechanism can work in the complex space environment. 2010 SPIE.

Linear fiber-optic image slicer is used more and more in spatial exploration and imaging system. In this paper  a plane arranging method of fiber-optic array based on Si-V grooves is established in order to improve the accuracy and reduce the cost of manufacturing. Firstly  the Si-V groove array is micro-machined with anisotropic etching process  then optical fibers are placed in the grooves orderly with plane arranging method. Secondly  the end surfaces of the device are polished  also the linear fiber-optic image slicer is packaged. Finally  some parameters are tested  including structure parameters  transmittivity and vibration test. Experimental results indicate that the maximum error accumulated in 2000 periods of the Si-V grooves is 0.5 m  the error of the height in Si-V grooves is less than 0.15m  the roughness of the end surface is less than 0.9nm. The transmittivity of the linear fiber-optic image slicer that without optical film is 51.46% at the wavelength of 632.8nm. After random vibration experiment  the ratio of the broken fiber increased by 0.1%. While the temperature reached 320C  the stress of epoxy will be 130Mpa  which is close to the limit resistance stress of 139Mpa  some cracks appeared.

Arrays of micro-sized LEDs which can be used as microdisplays have been demonstrated in recent years. In order to reduce the input and output connections to the arrays  we employ a matrix addressable architecture  in which all the pixels in each row are connected by a common metal line on the top of the window layer (top electrode) or at the base of substrate(bottom electrode). Decreasing the size of electrodes makes for minimizing the size of device. The optic and electric isolation and good ohmic contact are also helpful to obtain superior optical and electrical performance. We describe a procedure of fabrication of AlGalnP-based orange micro-LED by wet etching. The structure of devices is etched using both isotropic and anisotropic etchant. The pixel size is about 16um 20um  and there are 1000 818 pixels in the light emitting chip whose diagonal is 1-in.
