We also design several new coupling methods of laser and fibers  and discuss the advantages and the disadvantages of them. 2011 IEEE.   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：17/0  |  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.   Vertical-external-cavity surface-emitting lasers: Numerical simulation, and characterization (EI CONFERENCE) 会议论文  OAI收割 Optoelectronic Materials and Devices III, October 27, 2008 - October 30, 2008, Hangzhou, China 作者:  Qin L. 收藏  |  浏览/下载：16/0  |  提交时间：2013/03/25 Firstly  the vertical external-cavity surface-emiting lasers (VECSELs) device structure and model was given  and the output characteristic was simple calculated. Then  in experiment  the VECSELs were grown  bonded on to the heat sink  and optically pumped by high-power 808nm diode laser array with fiber output module  the light emission spectra were measured. Finally  The thermal characteristic of the VECSELs was investigated by changing the temperature of the substrate. 2008 SPIE.   Study on resonance absorption raman scattering in i2 liquid-core optical fiber (EI CONFERENCE) 会议论文  OAI收割 Nonlinear Optics: Technologies and Applications, November 12, 2007 - November 13, 2007, Beijing, China 作者:  Fang W.;  Yi W. 收藏  |  浏览/下载：17/0  |  提交时间：2013/03/25 The Raman scattering of I2 liquid-core optical fiber under the condition of resonance absorption in liquid-core optical fiber is studied in this paper. Iodine is dissolved in transparent benzene to make solution of I2 in benzene  and the absorption coefficients of the solution are measured at certain wavelengths. The absorption curve can be divided into non-resonance absorption region  pre-resonance absorption region  strict resonance absorption region  and post-resonance absorption region respectively. Resonance absorption Raman scattering experiments are conducted by a 532 nm frequency-doubled Nd:YVO4 laser  and the wavelength is in the strict resonance absorption region of solution of I2 in benzene. Compared with I2  the absorption of benzene can be neglected. Non-resonance Raman scattering of the solution is performed using a 632.8 nm He-Ne laser  and no spectrum lines of I2 are found. The study demonstrates that there is one spectrum line of I2 in the Raman scattering spectrum in the I 2 liquid-core optical fiber  but this line is not found in the spectrum of the non-resonance and resonance absorption Raman scattering of I2 solution in benzene using absorption cell. The experiments proved that I 2 Raman scattering  is greatly enhanced by using both resonance absorption and liquid-core optical fiber.   Study on technology of orientation and north-finding based on fiber optic gyroscope (EI CONFERENCE) 会议论文  OAI收割 2007 IEEE International Conference on Mechatronics and Automation, ICMA 2007, August 5, 2007 - August 8, 2007, Harbin, China Zhang Z.; Sun J.; Wu K. 收藏  |  浏览/下载：12/0  |  提交时间：2013/03/25 North-finding system provides true north azimuth information to all kinds of ground-based equipment. A dynamic automatic north-finder based on the modulation output of fiber optic gyroscope (FOG) is presented in this paper. In this scheme  the sine output signal of the FOG was sampled and disposed  and then the real north of surveyed point on the surface of earth was calculated. The deviation caused by the platform base tilt was compensated by an accelerator  Allan standard deviation is used to analyze the random drift of FOG  and establish the random error mode of FOG. The FOG north-finding and laser collimation theodolite are assembled to achieve orientation and aiming integral  which lays foundation for switching to project application. 2007 IEEE.
