Dual frequency and nematic LC materials were reported to be used in astronomical observations. However  nematic LC with its simple producing and driving method and multi-gray-level is promising in the application. We have investigated the nematic LC AO system and promoted its application for nearly ten years. Here  we reported our newest nematic LC AO system with bandwidth result of 3dB is 54.4 Hz  0dB bandwidth is 79.1Hz. 2012 IEEE.   The state of the art for Liquid crystal adaptive optics in astronomical applications 会议论文  OAI收割 2012 作者:  Xuan L. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/28 Design of heliostats field for the scale of 1MW solar power tower plant (EI CONFERENCE) 会议论文  OAI收割 2012 Asia-Pacific Power and Energy Engineering Conference, APPEEC 2012, March 27, 2012 - March 29, 2012, Shanghai, China 作者:  Zhang H.;  Wang Z.;  Wang Z.;  Zhang H. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 The development in basic technology and market strategy of solar thermal power techniques is booming rapidly due to the limited fossil resources and severe environmental problems all over the world. In this paper  the design method of heliostats field for the scale of 1MW solar power tower plant with latitude of 40.4N at the design point of the noon of spring equinox is introduced  which uses the multiplication of three efficiencies of cosine  atmospheric transmittance and intercept as the preliminary boundary limit to locate heliostats  while the spacing between heliostats is set not only for less shading and blocking  but also for the availability of installation and maintenance of heliostats. Furthermore  its optical performance tested by the software HFLD  is quite good  which has annual average efficiency of 71.36% and design point efficiency of 80%. 2012 IEEE.   Effect of the edge roughness of the pinhole in point diffraction interferometer on light diffraction 会议论文  OAI收割 2012 Lu Z.

First of all  this paper recommended the Splicing structure of CCD in the APRC Based on this  auto-focus method which is made use of the overlapping area of CCD mosaic structure was proposed  combined with the characteristic of the imaging mode. After analyzing of experiments about all kinds of focus-examine functions based on image processing  the gradient square function has been chosen. The experimental results show that the proposed auto-focus method for the APRC is proved to be feasible and real-time. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).   Design of compound Fresnel-R lenses for new high-efficient photovoltaic concentrator (EI CONFERENCE) 会议论文  OAI收割 Nonimaging Optics: Efficient Design for Illumination and Solar Concentration VII, August 1, 2010 - August 4, 2010, San Diego, CA, United states 作者:  Liu H.;  Liu H.;  Liu H. 收藏  |  浏览/下载：24/0  |  提交时间：2013/03/25 A new design of compound Fresnel-R concentrator is presented which is composed of two lenses: a primary lens (Fresnel lens) that works by total internal reflection at outer facets but refraction at inner facets  and a secondary lens that works by refraction. In contrast to previous Fresnel lens concentrator  this design increases the acceptance angle  improves the irradiance uniformity on the solar cell  and reduces the aspect ratio significantly. Another outstanding advantage of this concentrator is the fact that it mainly works by performing total internal reflection  reducing chromatic dependence as well as Fresnel losses. An optical efficiency more than 80% can be achieved. Moreover  in order to reduce the influence of manufacture accuracy and to increase the optical efficiency further  the central part of the bottom of the secondary lens which directly adhered to the solar cell is designed as a cone-shaped prism to collect the sunlight that doesn't reach the solar cell. 2010 SPIE.
