	An Image Highlights Removal Method with Polarization Principle 会议论文 OAI收割 2015 3rd International Conference on Machinery, Materials and Information Technology Applications (ICMMITA 2015), Qingdao, China, November 28-29, 2015 作者: Li F(李芳); Tian JD(田建东); Tang YD(唐延东); Wang Y(王琰) 收藏 \| 浏览/下载：32/0 \| 提交时间：2015/12/20 image processing highlight removal polarization information Stokes parameters specular reflection
	The cell thickness and twist angle measurement of twist nematic liquid crystal cell by rotation of a quarter-wave plate using fourier analysis method (EI CONFERENCE) 会议论文 OAI收割 Asia Display 2007, AD'07, March 12, 2007 - March 16, 2007, Shanghai, China Cui H.-Q.; Ling Z.-H. 收藏 \| 浏览/下载：24/0 \| 提交时间：2013/03/25 Proposed a new method of determining the cell thickness and the twist angle of twisted nematic liquid crystal cells a quarter-wave plate was inserted between the liquid crystal cell and the analyzer a stepper motor rotated the Retarder by 360 and measured the light intensity of every modulated point solved the stokes parameters of polarization light exiting from the liquid crystal cell using Fourier analysis method thereby determining the cell thickness and the twist angle. Experiments indicated that it is suitable for measuring the low-cell-gap accurately. In addition it also can be applied to the measurement of the cell thickness and twist angle of single polarizer reflected liquid crystal cell.
