	Study on infrared transparent radar double band-pass filter (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Mechatronics and Materials Processing, ICMMP 2011, November 18, 2011 - November 20, 2011, Guangzhou, China Jia H. Y.; Feng X. G. 收藏 \| 浏览/下载：27/0 \| 提交时间：2013/03/25 To realize the functions of infrared transparent as well as radar double- pass Band A Y loop and Y slot compound element Frequency Selective Surface (FSS) structure is proposed which takes an infrared transparent inductive mesh as a substrate. The proposed structure is analyzed based on Galerkin spectral method. The transitivity of infrared (3um-5um) as well as the radar double passed band with two resonance frequencies (31GHz and 54GHz) is discussed. The result reveals that this structure has function of infrared transparent as well as stable radar double-band filter with effective shielding effect on S-band and C-band radar electromagnetic waves. The design with multiple passband is suitable for radar/IR composite guidance and it also offers a kind of new thinking way of design for multi-mode compound guidance systems. 2011 Trans Tech Publications.
	Multi-parameters decoupling method with Lamb wave sensor for improving the selectivity of label-free liquid detection (EI CONFERENCE) 会议论文 OAI收割 2011 16th International Solid-State Sensors, Actuators and Microsystems Conference, TRANSDUCERS'11, June 5, 2011 - June 9, 2011, Beijing, China 作者: Zhou L. 收藏 \| 浏览/下载：27/0 \| 提交时间：2013/03/25 The anti-symmetric modes (A01 mode for low frequency A 03 mode for high frequency) and symmetric modes (S0 mode) produced by Lamb wave sensor are used to detect multi-parameters of a liquid such as its density sound velocity and viscosity. These modes are found to be very different to the parameters. For example the A01 mode is very sensitive to the liquid's density but the A03 mode is sensitive to its sound velocity. The measurements of the attenuation with S0 mode can give out liquid's viscosity after its density been determined by A 01 mode. That could be a way to distinguish an unknown liquid with high sensitivity or to solve the problem of the selectivity of label free detection on biosensors. 2011 IEEE.
	Non-uniformity correction in multi-CCD imaging system (EI CONFERENCE) 会议论文 OAI收割 2010 2nd International Conference on Mechanical and Electronics Engineering, ICMEE 2010, August 1, 2010 - August 3, 2010, Kyoto, Japan Tao M.; Ren J. 收藏 \| 浏览/下载：34/0 \| 提交时间：2013/03/25 The non-uniformity phenomenon exists in each channel of multi-CCD imaging systems. The factors which lead to the problem are complex. The conventional calibrating algorithms can not consider all of these factors and have poor effects. According to the characters of multi-CCD imaging systems a non-uniformity correction method based on the scene was proposed by adopting the traditional two-point correction theories. The correction coefficient of each channel image can be calculated via the linear relation between the two neighboring pixel lines in the two-channel images. Compared with the conventional two-point calibration and multi-point calibration methods contrastive calibrating results were obtained. This method does not need any standard lighted image as reference source which provides a real time way for calibrating the multi-CCD imaging systems in practical applications. 2010 IEEE.
	Research on high precision membrane mirror forming method (EI CONFERENCE) 会议论文 OAI收割 5th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Large Mirrors and Telescopes, April 26, 2010 - April 29, 2010, Dalian, China Liu C.-Y.; Jia J.-Q.; Jin G.; Zhong X.; Gu S. 收藏 \| 浏览/下载：20/0 \| 提交时间：2013/03/25 With the development of aeromechanics large light reflector that satisfies the diffraction of light becomes the dominant object of the optical operator. The assumption of designing reflector with organic membrane with reflecting layer plated emerges as the times require. based on an analytical solution of Poisson's equation and careful analysis of forming method the paper puts forward a conclusion that multi-electrode controlled electrostatic stretching membrane mirror is a better way than single-electrode controlled electrostatic stretching membrane mirror and also gives a preliminary comparative analysis of these two method. 2010 Copyright SPIE - The International Society for Optical Engineering.
