But we can do it using computer-generated holograms (CGH). The principle and design of the CGH have been discussed in the paper. Take the cubic suface as an example  The order separation of the CGH is analyzed theoretically and the simulation result of the order separation is given in the paper. We develop the binary process of the continuous CGH phase function and get the sample of the amplitude CGH. A CGH for testing a cubic phase plate with duty cycle 0.5 is fabricated by using e-beam lithographic techniques. In this situation  the contrast of the interference fringe pattern can achieve a level of 99.4% by calculation. 2012 IEEE.   The optical design of cubic phase plate testing system (EI CONFERENCE) 会议论文  OAI收割 2011 Symposium on Photonics and Optoelectronics, SOPO 2011, May 16, 2011 - May 18, 2011, Wuhan, China 作者:  Zhang X.;  Zhang X.;  Zhang X.;  Zhang Y. 收藏  |  浏览/下载：18/0  |  提交时间：2013/03/25 Computer-generated holograms (CGH) have been widely used for years in optical testing of aspheric surfaces in combination with Fizeau interferometers. With the development of diffraction optics  computer technology  and micro-processing technology  the accuracy of the CGH testing can achieve a hundredth of a wave  and the cost is reduced greatly. CGH is capable of producing an optical wavefront with any desired shape. So it is fascinating and will have good prospects to test free-form surfaces using CGH. As the CGH can create any wavefront shape  it can also be used in unsymmetrical aspherical surfaces testing. Taking the cubic surface as an example  this paper gives a method to test unsymmetrical surfaces. This paper gives the design to test a cubic surface. And the separation of the diffraction orders and the binary process of the continuous CGH phase function are discussed in detail. The alignment tolerance of the test system and the CGH fabrication tolerance are analyzed. We also present an idea using a CGH and two spherical lenses as null lens to test the cubic surface when the surface deviation is great. 2011 IEEE.   Study on sensing properties of a temperature-independent high pressure sensor base on tapered FBG (EI CONFERENCE) 会议论文  OAI收割 International Symposium on Photonics and Optoelectronics, SOPO 2010, June 19, 2010 - June 21, 2010, Chengdu, China 作者:  Liu Y.;  Zhang Y.;  Zhang X.;  Zhang X.;  Zhang X. 收藏  |  浏览/下载：20/0  |  提交时间：2013/03/25 The sensing properties with strain and temperature of tapered FBG had been researched both theoretically and experimentally. Based on tapered FBG and thin-wall strain cylinder structure  a novel temperature-independent high pressure sensor was fabricated and investigated. The tapered FBG performed as a chirped grating  whose bandwidth and reflection power broadened and increased when the pressure applied on it. Moreover  the bandwidth and the reflection power were temperature-independent. So the value of the strain can be obtained by detecting the reflection power. This method effectively solved the cross-sensitivity problem. The experiment results indicated that this sensor provided a measurement range of 040MPa with a sensitivity of 0.04w/MPa  low cost and good application prospect. 2010 IEEE.   OFDM Baseband Modulation Technology based on VHDL 会议论文  OAI收割 2010 Lin L.; Qiao Y.
