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 effect of laser spot strengthened surface in elasto-hydrodynamic lubrication 会议论文  OAI收割 9th International Conference on Contact Mechanics and Wear of Rail/Wheel Systems, CM 2012, Chengdu, China, August 27, 2012 - August 30, 2012 作者:  Xing XH(邢旭辉);  Yang Z;  Zhan LJ;  Yang MJ(杨明江);  Lin HQ 收藏  |  浏览/下载：15/0  |  提交时间：2017/06/20 Experimental simulations  High contact pressures  Laser spots  Rail/wheel  Rough surfaces  Test machine  Test specimens  Tribology performance   Microstructure and mechanical properties of CrN coating deposited by arc ion plating on Ti6Al4V substrate 期刊论文  OAI收割 Surface & Coatings Technology, 2011, 卷号: 205, 期号: 19, 页码: 4690-4696 Z.

This method adopts a collimator tube that can be measured as a target fixed to the test table  and the target corresponds to the angular position of the test table. In the process of the table rotating  the camera will to keep track of the objective at a high speed. Due to the high sampling frequency of the high-speed camera  instantaneous angular rate of test table can be measured. With pixel subdivision technology  its measuring accuracy can be up to 0.02 pixels. We use this methods measured a low-speed test table's angular rate and analyzed the data. The error analysis shows when the rate of the test table is 0.20/s  the accuracy of the method can achieve 0.0220%. 2009 IEEE.   Antioxidant and metabolic responses induced by cadmium and pyrene in the earthworm Eisenia fetida in two different systems: contact and soil tests 期刊论文  OAI收割 CHEMISTRY AND ECOLOGY, 2009, 卷号: 25, 期号: 3, 页码: 205-215 Zhang, Xiang; Lu, Yonglong; Shi, Yajuan; Chen, Chunli; Yang, Zhi; Li, Yedan; Feng, Yan 收藏  |  浏览/下载：35/0  |  提交时间：2015/08/07 cadmium  pyrene  glutathione-S-transferase (GST)  catalase (CAT)  earthworm (Eisenia fetida)  contact test  soil test  acute and chronic exposure  OECD soil
