Altazimuth photoelectric theodolite level shaft U-type and T-type structure  but with the expanding field of applications of photoelectric theodolite  the horizontal shaft structure occur great changes. For example  in the marine environment  shipboard conditions  the instrument has a waterproof  corrosion-resistant  easy maintenance and other functions  while carrier-based optoelectronic devices from a single visible television configure the development of integrated infrared system and ranging system as one of the single-station measurement system  due to the spherical structure has sufficient internal space exactly adapted to this need. In this paper  the horizontal axis of a spherical four-way structure. From aspects of the spherical four-way split in the form and shafting design and finite element analysis of the detailed design. A spherical four-way horizontal axis system  diameter 550mm  weight 19kg sphere  in the 40kg load  the maximum deformation of 3.3m  fully meet the requirements. The shaft of the structure of the shaking is less than 2 arc seconds  the vibration test  the re-examination instrument accuracy change is less than 1 arc seconds. Verify that the structure is stable and reliable. 2012 IEEE.  
Effect of thickness on the structural, electrical and optical properties of ZnO films deposited by MBE (EI CONFERENCE) 会议论文  OAI收割

A set of ZnO films of different thickness have been deposited on sapphire substrates using molecular beam epitaxy (MBE) by varying the growth time and the effect of film thickness on the structural  electrical and optical properties have been investigated. The X-ray diffraction (XRD) results indicate that the full width at half maximum (FWHM) of the (002) diffraction peak is decreased as the film thickness increasing  and the stress along c-axis is stable. Scanning electron microscope (SEM) measurement shows that the grains become more uniform as the film grows thicker and the film surface present distinct hexagon shape as the film is grown up to a thickness of 500nm. The optical absorbance  Hall mobility and photoluminescence (PL) intensity are increased in accordance with the thickness of the film. (2011) Trans Tech Publications  Switzerland.

Propose a new measurement system of autocollimation form laser grating heterodyne interferometer. Take grating diffraction and polarization optics as theoretical foundation  second  furthermore  combined with electronics knowledge to analyze the system. First  make use of autocollimation diffraction of grating  measurement information obtained by dual-frequency laser belongs to ac signal  the interferometer measurement system take grating pitch as measuring datum  the structure is simple  possess great gain and high signal-noise ratio  therefore  stable  completely overcome the disadvantages of DC level drift caused by light intensity variation of single-frequency laser  system can achieve nanometer resolution. 2010 IEEE.  reduce the impact of environmental factors  easy to install and debug  measurement error is small
