	The application of digital signal processing (DSP) for the real time solving of artillery fire control exterior trajectory (EI CONFERENCE) 会议论文 OAI收割 2012 IEEE 3rd International Conference on Software Engineering and Service Science, ICSESS 2012, June 22, 2012 - June 24, 2012, Beijing, China 作者: Li D. 收藏 \| 浏览/下载：140/0 \| 提交时间：2013/03/25 Method of gain firing data by calculate the group of differential equation has the advantages of high repeatability and high accuracy But much of the CPU time is occupied by the task of re-iteration in computational processing. Therefore it is not the real time processing. This paper introduces a method to quickly determine angle of firing by iteration method which realizes Runge-Kutta method for the equations of exterior ballistic according to the model of mass center motion of projectile. Moreover it also provides the flow of real-time integral solution and be proved by the simulation of MATLAB. Its accuracy satisfies the requirements. This work can be as reference for the design of opt-electrical fire control system and the demonstration work. 2012 IEEE.
	Study of horizontal shafting with spherical four-way structure (EI CONFERENCE) 会议论文 OAI收割 2012 International Conference on Optoelectronics and Microelectronics, ICOM 2012, August 23, 2012 - August 25, 2012, Changchun, China 作者: Yang L.; Yang L. 收藏 \| 浏览/下载：29/0 \| 提交时间：2013/03/25 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.

Still here gives out reference codes of update data package which generated by the ground. 2012 IEEE.
	The effect on tolerance distributing of an off-axis three mirror anastigmatic optical system with wavefront coding technology (EI CONFERENCE) 会议论文 OAI收割 Optical System Alignment and Tolerancing II, August 10, 2008 - August 11, 2008, San Diego, CA, United states 作者: Yan F.; Zhang X.-J.; Yan F. 收藏 \| 浏览/下载：34/0 \| 提交时间：2013/03/25 The wavefront coding technology is known as a system-level technology which can extend the depth of focus of optical system by innovative optical design and image restoration. This technology can control misfocus related aberrations including misfocus astigmatism and Petzval curvature temperature-related misfocus in digital imaging systems. It can also help optical system tolerate more residual error in optical manufacturing and alignment besides misfocus. The brief introduction of wavefront coding technology and the wavefront coded TMA system under research is presented respectively in part 1 and part 2. The "MTF similarity" is defined to describe the relationship among MTF at different position or different fields in the third part. It is also shown in this part that the MTF similarity of wavefront coded system is much higher than the normal system within a large range. In part 4 comparison between the origin system and the new system with wavefront coding technology is provided after multiple errors are introduced from which it can be observed that the system with wavefront coding technology can tolerate much bigger error than origin system. The error tolerance is re-distributed according to a new criterion based on MTF similarity. If the MTF similarity is less than a certain value it can be regarded that the system can tolerate the residual error. The new error tolerance is displayed and it is shown that the wavefront coding technology can also loosen the error distributing besides extended the depth of focus.
	Integrated optical amplifiers based on rare-earth doped (red) oxide glasses (EI CONFERENCE) 会议论文 OAI收割 International Symposium on Photonic Glass (ISPG 2002), October 14, 2002 - October 17, 2002, Shanghai, China 作者: Chen B.; Chen B. 收藏 \| 浏览/下载：36/0 \| 提交时间：2013/03/25 Oxide glasses have been used since long time to host a number of active compounds first of all rare-earth (RE) ions for lasing. Recently the advantages offered by guided-wave format namely the small size the high pump power density and the larger flexibility in design and fabrication led to the development of fiber lasers and amplifiers based on Er3+-doped glasses. Currently a growing activity is aimed at achieving large optical gain in Er3+-doped planar waveguides having in mind the single-chip realization of integrated optical amplifiers and lasers. The aim of the present paper is to provide a quick overview of this area and to briefly discuss possible future developments.
