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 Laser beacon adaptive optics ophthalmoscope for retinal multilayer imaging (EI CONFERENCE) 会议论文  OAI收割 2nd International Symposium on Bioelectronics and Bioinformatics, ISBB 2011, November 3, 2011 - November 5, 2011, Suzhou, China 作者:  Xuan L.;  Zheng X.;  Li D. 收藏  |  浏览/下载：16/0  |  提交时间：2013/03/25 A flood-illuminated adaptive optics ophthalmoscope for retinal multilayer imaging is introduced in this paper. By arranging an alterable stop in the illumination path  the illuminated area of retinal layer can be changed. A laser beacon for wavefront sensing is formed when the stop is a narrow aperture. The large aperture allows flood illumination and expands imaging field. A moveable imaging camera can focus on different layers of the retina. In the confirming experiment  a subject who was a 25-years-old normal health Chinese male was imaged. We got clear images of photoreceptor layer  blood vessels and nerve fiber layer. 2011 IEEE.   The synthesis and field emission property of carbon nanotubes on carbon fibers substrate 会议论文  OAI收割 2007 Zeng L.

In this experiment  we mainly studied the characteristics of field emission from the CVD diamond films. The motivation for the experiment is to gain some insight into a possible emission mechanism. The diamond films are grown using a hot filament chemical vapor deposition  basing on the diamond micro-grits on silicon substrates. And the diamond micro-grits are deposited on silicon substrates using electrophoresis coat method  through a solution of diamond micro-grits in ethyl alcohol. This study has revealed that emission can be obtained at fields as low as 1.8V/m. And the field emission measurements were carried out at a pressure of 10-4Pa.   Transmission characteristics of air core photonic band gap fiber - art. no. 60250H 会议论文  OAI收割 2006 Wang W.

An arrangement of air holes running along the full length of the fiber provides the confinement and guidance of light. The light is confined in the silica core along the fiber axis. This fiber has endlessly single mode  special dispersion characteristics and so on. Using a vectorial effective-index numerical method  we investigated the dispersion characteristics of a microstructure fiber with honeycomb cladding structures. The dispersion  dispersion slope  and Kappa parameter can be designed neatly by changing the air hole size and the separation of the holes in fiber cladding. We demonstrated the Microstructure fiber with large absolute value of normal dispersion and negative dispersion slope at the wavelength of 1550nm. Conventional communication non-shifted single-mode fibers and nonzero-dispersion shifted fibers (NZ-DSF) can be compensated efficiently using the microstructure fiber at the wavelength around 1550nm.   Field emission performances of diamond powders coated with metal (EI CONFERENCE) 会议论文  OAI收割 19th International Vacuum Nanoelecronics Conference and 50th International Field Emission Symposium, IVNC and IFES 2006, Jul 17 - 20 2006, Guilin, China 作者:  Liu L.;  Li M.;  Wang W.;  Wang W.;  Liu L. 收藏  |  浏览/下载：12/0  |  提交时间：2013/03/25 No abstract available
