In the large-diameter opto-electronic device tracking equipment  by full analyzing the support structure of the primary mirror  the primary mirror usually uses the combination of the bottom support and the lateral support. Because both the bottom support and the lateral support are installed on the primary mirror chamber's base plate  after changing the welded structure of the primary mirror chamber structure to the cast structure and improving the stiffness of the primary mirror base plate  the stiffness of the base plate will show in the amount of sloshing of the primary mirror relative to the primary mirror chamber and therefore influences the tracking accuracy of the opto-electronic device. During the assembling and adjusting of the primary mirror in the actual process of working on the project  the amount of sloshing of the primary mirror is reduced significantly. The results show that in working on the primary mirror support  as is found that the amount of sloshing of the primary mirror relative to the primary mirror chamber is comparatively large  the forms and structure stiffness of bottom support and lateral support should be considered  together with that the stiffness of the primary mirror chamber acting as the basis is playing the crucial role. 2011 IEEE.

Transmit array photogrammetric camera can obtain image which is high geometric fidelity and high photogrammetric quality. However  the single chip array CCD image sensor camera can't meet the need of measuring precision and photogrammetric covering area. In order to obtain large numbers of information and extensive photogrammetric covering area  we must increase field of vision angle and improve photogrammetric covering area. And all these objects can be realized by exterior field of vision assembling photogrammetric camera. Two side work must be done before images  which obtained by exterior field of vision assembling photogrammetric camera  be used in photogrammetry. First  all assembling camera focal plane need be converted to a benchmark coordinate focal plane to realize camera digital assembling. Second  images must be re-sampled and processing. Because of coordinate conversion  two images from different assembling cameras can be established function relation  which a pixel of image from a camera is corresponding to a pixel of another image from different camera. But through this conversion  some pixels maybe extrusion together and other pixels separate on an image area. So interpolation direction finding(IDF) is used to obtain these pixels and realize image re-sampling. In this paper  the structure of exterior field of vision assembling photogrammetric camera is analyzed  and the coordinate conversion method of exterior field of vision assembling photogrammetric camera and image gray re-sampling method also can be discussed. All the works are based to data pretreatment of exterior vision assembling photogrammetric camera.

We study insertion losses of optical switch when the laser beam is propagating during the free space between two single mode fibers (SMFs) and the related assemblage challenges  Then a new packaging structure is developed for the hybrid-integration of free-space MOEMS (micro-opto-electro-mechanical systems) chip with a silicon micromachined submount to improve alignment accuracy. The submount is designed to accommodate various free-space MOEMS chips with minimal active optical alignment  thus reducing the packaging cost. The silicon submount has a central recess to place the MOEMS chip in  sixteen V-grooves for optical fibers  and micropits for micro ball lenses  all bulk micromachined at the same time by a single anisotropic wet etching step. A corner compensation technique is employed to prevent erosion of the convex corners  where different geometries meet. Through this assembling method  the fiber  micro ball lens can be aligned preciously thus reduced lateral and angular misalignment between them. Then total insertion losses can be decreased.
