The Matlab simulation results prove that the encoding and coding methods are feasible. The test showed that the cubage of encoder was quite small and the diameter of the encoder can be controlled within 100mm  its resolution can reach 24 bits i.e. 0.0772. The feasibility of encoding and coding method was further proved. 2011 IEEE.   Incident angle of parallel light measurements based on the optical vernier principle 期刊论文 2010, 2010 Chen Feifan; Hong Zhiwei 收藏  |  浏览/下载：6/0 多脉冲游标扩时测距算法及其应用设计研究 学位论文 2009, 2009 房永强 收藏  |  浏览/下载：1/0  |  提交时间：2016/02/14 游标扩时  多脉冲测距  微波调制  相关检测  网线测量  Time-domain Expansion with Vernier Principle  Multi-Pulse Ranging  Microwave Modelation  Cross Correlation  Measuring of Network Cable   光纤布拉格光栅法布里-珀罗滤波器及其在可调谐窄线宽光纤激光器中应用的研究 学位论文 2009, 2009 陈敏秀 收藏  |  浏览/下载：2/0  |  提交时间：2016/02/14 光纤激光器  光纤光栅  法珀滤波器  游标原理  窄线宽  Fiber laser  Fiber Bragg grating  Fabry-Perot filter  Vernier principle  Narrow linewidth
