	Design of optical elements for imaging the earth's plasmasphere (EI CONFERENCE) 会议论文 OAI收割 International Symposium on Photoelectronic Detection and Imaging, ISPDI 2007: Optoelectronic System Design, Manufacturing, and Testings, September 9, 2007 - September 12, 2007, Beijing, China 作者: Chen B.; Chen B.; Wang X.-K. 收藏 \| 浏览/下载：31/0 \| 提交时间：2013/03/25 Studying the distribution of He+ in Earth's plasmasphere by detecting its resonantly-scattered emission at 304A will record the structure and dynamics of the cold plasma in Earth's plasmasphere on a global scale. EUV imaging systems usually utilizes near normal incidence optics including multilayer mirror and filter. In this paper the space condition of the Earth's plasmasphere to confirm the expected performance of mirror and filter for this task were analyzed and some guidelines for the design of the optical elements were introduced. In order to achieve higher response at 304A and reduce 584A radiation for the optical system a new multilayer coating of Mo/Si with UOx (x=2-3) was developed and it is indicated that promising filter material is Al/C with a nickel mesh. In addition we compute the reflectance of multilayer mirror based on optical constants and the transmission of the filter based on atomic scattering factor. The results show the multilayer mirror has high reflectance of 26.27% at 304 Aand low reflectance of 0.60% at 584A. Finally the conversion efficiency of mirror coupled with filter is 6.88% at 304A and 0.01% at 584 A.
	All reflective zoom systems for infrared optics (EI CONFERENCE) 会议论文 OAI收割 International Optical Design Conference 2006, June 4, 2006 - June 8, 2006, Vancouver, BC, Canada 作者: Wang Y.; Yang H.; Zhang T.; Wang Y.; Wang Y. 收藏 \| 浏览/下载：30/0 \| 提交时间：2013/03/25 The results of design effort for infrared zoom systems using all reflective aspheric surfaces are described. Issues such as the paraxial design theory and aberration balancing are discussed in detail. Two all reflective zoom optical systems are disclosed clearly. Both of them are to be used with uncooled infrared detectors. The first design is an unobscured three mirror zoom system without any intermediate image and the second is a three mirror system with central obscuration which forms an intermediate image. With the design theory further developed this kind of systems can be designed for cooled infrared detectors for which cold stop matching is an important issue. 2006 SPIE-OSA.
