Abstract:First, the basic concepts and the applications of close-range 3D laser scanning techniques were described. Then, the knowledge of these new techniques was strengthened through the comparison of passive 3D imaging techniques and active 3D imaging techniques and the comparison of three common techniques of laser ranging. After that, the principle and the basic steps of close-range 3D laser scanning based on triangulation were explained. The development status of these new techniques was also presented. At the end, the difficulties and the prospects of close-range 3D laser scanning techniques were discussed.

Abstract:Along with the development of space techniques, the mechanical structures of remote sensors become more and more precise and complex. How to design the products with high quality quickly and precisely is an urgent affair. Because of the features, such as high efficiency, direct visible, rich information and easy analysis, 3D CAD techniques become more and more attractive, Taking an optical mechanical scanner for example, the 3D CAD design method and thought of a space optical remote sensor using SolidWorks is presented in this paper.

Abstract:According to the basic idea of the traditional two-point correction method, a new IRFPA non-uniformity correction algorithm based on the scene is developed. Taking use of the correlation of the gain ratio between detector and its adjacent cell, the gain and offset correction can be realized by iteration and the image non-uniformity can be reduced gradually.

Abstract:In this paper, a new enhancement algorithm is presented based on the characters of infrared dim-small target images. At first, the image background is suppressed by setting a threshold. Then, both gray density and gray interval of the histogram are equalized. This algorithm has the features of small calculation, excellent image enhancemcnt and real-time performance.

Abstract:When flying on orbit, with the change of environment and time, the response capability of a space camera must be attenuated. So it is necessary for a space camera to have a spaceborne radiant calibration. This can not only improve the precision of data but also follow and inspect the response capability of the space camera. In this paper, the spaceborne radiant calibration technologies of space cameras, especially of the newest pushbroom space cameras are presented.

Abstract:Acquisition of high resolution images is the goal for which people are always seeking. The technology for rebuilding high resolution image is an important method for getting high resolution images. This paper analyses the element of rebuilding high resolution image, summarizes the characteristics of various rebuilding methods and shows the development, environment and foreground of high resolution image rebuilding.

Abstract:如何识别处于杂波环境中的静止目标，这是最复杂的目标探测问题之一。在这种情况下，目标与平均背景之差（或者信号与噪声之比）较之背景的起伏变化是小的。这是经过精心伪装的目标在长波红外（8μm～12μm）波段内的基本特征．人们试图利用具有高空间分辨率的焦平面列阵通过前视红外成像传感器来解决信噪比问题，但成功率有限。在有严重杂波干扰的环境中，宽带中波红外（3μm～5μm）和长波红外传感器探测伪装目标的能力受到了限制。

Abstract:硅晶片是微电子工业的基本建筑模块。用于制备集成电路的硅晶片的尺寸在稳步增大，因为晶片越大，每一加工步骤中所产生的部件也就越多．当晶片的直径增加到300mm或者更大时，它们就会变得越来越容易损坏，而且在制造期间容易受到产生的应力的影响。
