光干涉仪 meaning in English
optical interferometer
Examples
- A type of small - sized interferometer is reported , which makes use of the coupling of optical fiber and gradient index lens ( grin ) to form parallel light beams
摘要介绍一种超小型光纤导光干涉仪,它利用光纤和自聚焦透镜的耦合来形成平行光路,利用半反和全反光学膜片分光。 - Fiber - optic fabry - perot sensor is a kind of high precision interferometric fiber - optic sensor , so this kind of sensor has a bright future . this sensor can be classified into 3 kinds of sensors by their demodulation device . these are intensity modulation / demodulation fiber - optic fabry - perot sensor , phase modulation / demodulation fiber - optic fabry - perot sensor and white - light interferometer modulation / demodulation fiber - optic fabry - perot sensor
按照信号解调装置的不同该种传感器可分为三类:强度调制解调型、相位调制解调型和白光干涉仪调制解调型光纤fp传感器,其中后两种采用宽光谱光源,是白光干涉型光纤fp传感器。 - Therefore this kind of sensor is best sensor for smart structure . at first , we studied the theory of light interferometry , multi - light interfeormetry and white - light interferometry . then we analysed the working principle of white - light interferometric fiber - optic fabry - perot sensor , and get two kinds of ways for demodulation : directive ( phase ) and inderective ( white - light interferometer ) modulation / demodulation ways
本文首先利用光的干涉理论、多光束干涉理论和白光干涉理论分析了白光干涉型光纤fp传感器的工作机理,由此得到了白光干涉型光纤fp传感器的两种解调方法:直接解调的相位调制解调法和间接解调的白光干涉仪调制解调法。
