In this paper  a micro Fourier transform infrared spectrometer (FTIR) based on spatial modulation mode was designed. This spectrometer has the advantages of high stability and simplified configuration. It also promises optical path differences (OPD) with high precision  as MOEMS technology is used in manufacturing the key components. The simulation and the experiments with regard to this FTIR configuration have been done. Firstly  the diffraction effect of the micro multi-step mirrors (MMSMs) is studied. We discuss the influence to the reversed spectrum by different mirror widths and different diffraction distances. Secondly  we simulate and analyze the influence of the source solid angle to the spectral resolution. Thirdly  we set up the theoretical model of the collimation error which is mainly from the defocus of the optical system and analyze the result caused by the collimation error. Fourthly  a new discrete Fourier transform arithmetic using least-squares cosines progression (LSCP) is proposed which can reconstruct the spectrum with nonuniform sampled signals. Finally  the MMSMs are fabricated used the MOEMS technology and the structural parameters are tested. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).   Ultraviolet photodetector fabricated from atomic-layer-deposited ZnO films (EI CONFERENCE) 会议论文 Shan C. X.; Zhang J. Y.; Yao B.; Shen D. Z.; Fan X. W.; Choy K. L. 收藏  |  浏览/下载：20/0  |  提交时间：2013/03/25 Zinc oxide (ZnO) films have been prepared on glass substrate in layer-by-layer mode using an atomic-layer deposition (ALD) technique  and a metal-semiconductor-metal structured photodetector has been fabricated on the ZnO films employing interdigital Au as metal contacts. The photodetector shows a cutoff wavelength at around 390 nm and has an obvious responsivity in the whole UVA spectral range. Because the response of the ZnO photodetector covers the whole UV solar irradiation that can reach the earth  the photodetector promises to be useful in monitoring UV solar irradiation to protect people from harm caused by the solar irradiation. Furthermore  the capability of preparing large-area uniform ZnO films of ALD makes it favorable for possible mass production of this kind of photodetector. 2009 American Vacuum Society.   Health IT Offers both Promise and Problems 期刊论文 Applied Clinical Trials, 2009 作者:  JillWechsler 收藏  |  浏览/下载：2/0  |  提交时间：2020/01/13 Promises  Problems  Economic  Stimulus  Electronic  Health  Records  Medical  Errors  Public  Confidences  Health  Insurance  Portability  and  Accountability  Act  Electronic  Health  Information   High energy long duration frequency-doubled Nd:YAG laser and application to veins occlusion (EI CONFERENCE) 会议论文 High-Power Lasers and Applications III, November 8, 2004 - November 11, 2004, Beijing, China Zhang L.; Yang G.; Li D.; Lu Q.; Gu H.; Zhu L.; Zhao Z.; Li X.; Tang Y.; Guo J. 收藏  |  浏览/下载：20/0  |  提交时间：2013/03/25 Laser treatment represents an attractive option to other methods of vessel diseases especially varicose veins. A long pulse (30-50ms) 532nm laser (Fig.1) is used in our experiments with the pulse duration matching the thermal relaxation time of the vessels and the green laser matching the absorption spectrum peak of the blood. Laser irradiates nude vein vessels directly or exterior skin to finish operation faster and to acquire the practical data for upper enteron varicose vein treatment in several animal experiments performed in vivo. The 5J-energy pulse allows us to finely occlude rabbit or dog's vein vessels up to 2 mm in diameter when irradiating them off external skin (Fig.2). Blood vessels are occluded at once and later biopsy specimens show the immediate and long-term lasting occlusion effect. While irradiating vessels directly (Fig.3)  the vessels are usually irradiated to perforate  detailed causes are still under investigation. Animal experiments show long pulse green laser therapy is a safe and effective solution to the vein's occlusion  which promises such laser with high energy of each pulse and 30-50 ms duration is an ideal candidate for vessel diseases treatment.
