InP/In0.82Ga0.18As/InP heterostructure used for infrared detector were grown on (100) S-doped InP substrates using two-step growth technique by low temperature metal-organic chemical vapor deposition. The growth was performed using TMIn  TMGa  AsH3  and PH3 as growth precursors in a horizontal reactor. The substrates on a graphite susceptor were heated by inductively coupling RF power  their temperatures were detected by a thermocouple  and the reactor pressure was kept at 10000 Pa. The growth structure of detector included In0.82Ga0.18As buffer with the thickness of 100 nm  In0.82Ga0.18As absorption layer with the thickness of 2.8 m  and the InP cap with the thickness of 0.8 m. The planar type of p-i-n detector was fabricated by Zn diffusion. The properties of In0.82Ga0.18As detector were studied  the curves of the I-V characteristics  the range of response spectrum  and the detectivity (D*) were obtained.

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.

Metallic mesh has been widely used in electromagnetic interference windows. While the duty ratio of curved mesh equals to planar mesh'  the theory of planar mesh may be applied to curved mesh according to equivalent-circuit model. So the idea that latitude lines intersect latitude lines to form isometric mesh on the concave of a sphere is put forward  and the method of fabricating the mesh by concentric optical scan is introduced. The movement parts of equipment consist of an erection turning  a horizontal dividing and a pitching dividing spindle. Firstly  a spherical substrate is fixed on the horizontal dividing spindle that has been set horizontally on the erect turning spindle  the substrate revolves around the axis of the erect spindle  the tube of object lens that is fixed on the pitching dividing spindle steps at pitching direction  and a revolving circuit of the substrate corresponds to a step of the tube. Gradually  a set of latitude lines is attained. Afterward  the substrate makes a quarter turn around the horizontal spindle  another orientation latitude lines are also gained. Thus  the isometric mesh on the concave of a spherical substrate is gained. The process comprises surface cleaning  coating photoresist  laser direct writing  development  evaporated film  dissolving photoresist and plating. The fabricated spherical mesh has a line width of 7 m and a period of 600m. Experiment shows that infrared transmission and electromagnetism shield efficiency of the metallic mesh are relatively consistent with theoretical value.
