The device is a compact  high precision  ultraviolet-vacuum  ultraviolet spectral radiometer  and is used to measure atmospheric solar backscattering spectral radiance and solar spectral irradiance. Noise of the system is analyzed and Numeric accumulation and synchronous demodulation was used to decrease the noise and the zero-drift of the instrument. The solar irradiance at altitude 830 km in 160-400 nm and the backscattering solar spectral radiance in the ultraviolet ozone absorption band at 12 wavelengths from 250 nm to 340 nm are obtained. Test results on orbit show that all the requested function is met successfully and the performance is stable. 2011 IEEE.   Bubble diagnosis and prediction of the 2005-2007 and 2008-2009 chinese stock market bubbles 期刊论文  iSwitch采集 Journal of economic behavior & organization, 2010, 卷号: 74, 期号: 3, 页码: 149-162 作者:  Jiang, Zhi-Qiang;  Zhou, Wei-Xing;  Sornette, Didier;  Woodard, Ryan;  Bastiaensen, Ken 收藏  |  浏览/下载：21/0  |  提交时间：2019/05/10 Stock market crash  Financial bubble  Chinese markets  Rational expectation bubble  Herding  Log-periodic power law  Lomb spectral analysis  Unit-root test   Modulation transfer function measurement of sampled imaging systems in field test (EI CONFERENCE) 会议论文  OAI收割 5th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optical Test and Measurement Technology and Equipment, April 26, 2010 - April 29, 2010, Dalian, China 作者:  Yang L.;  Zhang J.;  Zhang J.;  Zhang J.;  Wang J. 收藏  |  浏览/下载：27/0  |  提交时间：2013/03/25 A digital mirror device (DMD) based light projector was developed as the target generator in modulation transfer function (MTF) measurement. In order to overcome the sampling-scene phase effect in MTF measurement of sampled imaging systems  a method using random targets is introduced to yield a phase-averaged MTF. The main potential problem of implementing this method is the fact that the stationary assumption of the random targets may be vitiated in practical measurement  especially in field test due to the ill condition. We provide an efficient model-independent way of analyzing and isolating the spectral contents arising from these additional contributions to MTF measurement. Algorithms with adaptive parameter selection were also developed for spectral estimation of the test image in order to overcome the challenge brought by the size limit of the test matrices for one certain field of view derived from the isoplantic region. The MTF measurement of a CCD video imager is used to demonstrate the measurement technique and illustrate the benefits over other methods. In order to validate the results  comparisons have been made between MTF measurements of imager implemented using this method and bar target direct measurements. 2010 Copyright SPIE - The International Society for Optical Engineering.   White-light spectral scanning interferometry for surface measurement system (EI CONFERENCE) 会议论文  OAI收割 6th International Symposium on Precision Engineering Measurements and Instrumentation, August 8, 2010 - August 11, 2010, Hangzhou, China 作者:  Wang C. 收藏  |  浏览/下载：27/0  |  提交时间：2013/03/25 The paper introduces the white-light spectral scanning interferometry for surface measurement. This interferometry can be used to measure the roughness of both smooth surfaces and those with large step heights. This real-time surface measurement can be achieved using acousto-optic tuneable filtering (AOTF) technique without mechanical scanning. At first  the structure and principle of this interferometry is introduced. Then the algorithm of the surface roughness measurement is proposed. What's more  the experiment with standard test piece is conducted. Compared with the traditional laser-light interferometry  the data shows that the proposed method has a higher accuracy which is proved to be nano-scale. A conclusion is given at last in which the superiorities and the limitations of the proposed system were discussed. 2010 SPIE.   The performance test and the application of CCD (EI CONFERENCE) 会议论文  OAI收割 International Symposium on Photoelectronic Detection and Imaging 2009: Advances in Imaging Detectors and Applications, June 17, 2009 - June 19, 2009, Beijing, China 作者:  Wang S.-R.;  Qu Y.;  Zhang Z.-D. 收藏  |  浏览/下载：17/0  |  提交时间：2013/03/25 The e2v technologies' CCD sensor CCD57-10  which will be used as a detector in the Limb UV Imaging Spectrometer  is tested at first. Then the spectral responsivity calibration of the whole Imaging Spectrometer simply is described. The error analysis and the correction of the test of CCD's parameters under good repeatability and stability indicate that the properties of the CCD are suitable to the Limb UV Imaging Spectrometer. The spectral responsivity calibration and the theoretical calculation of the whole Imaging Spectrometer are within an acceptable error level. 2009 SPIE.   Quantative inversion based on hyperspectral data for soil salinization in the ecological corridor of tarim river, xinjiang,china 会议论文  OAI收割 2008 IEEE International Geoscience and Remote Sensing Symposium, Boston, MA, United states, 2008 Cun; Chang1; 2; Xi; Chen1; Anming; Bao1; Geping; Luo1 收藏  |  浏览/下载：17/0  |  提交时间：2011/08/23 Differential equations - Inverse problems - Problem solving - Regression analysis - Remote sensing - Rivers - Salinity measurement - Soils - Field sampling - Field test - Hyperion - HyperSpectral - Hyperspectral Data - Hyperspectral remote sensing - Key factors - Regression model - Sampling methods - Soil salinity - Soil salinization - Spectral estimation - Surface soil - Tarim river - Xinjiang
