Application of the Optical Interference Method
in Angle Measurement
Abstract : The optical angle measuring is an effective method to measure an angle, it is adjustable and has the characteristics of high precision. This paper introduces the optical interference measuring method in details, which is based on the principle of optical interference and has the highest precision. In this paper, the application of optical interference measuring method in small or big angle measurement and in the rotation angle measurement has been summarized. Also in the paper advantages and limitations of each method are analyzed. At last, the future prospects of angle measurement by optical interference method are pointed out.
