OBF:光拍频
“光拍频”的英文术语为“Optical Beat Frequency”,在学术和电子工程领域,为方便书写和引用,常将其缩写为OBF。该术语描述了当两束频率相近的光波相互叠加时,产生周期性强度变化的现象,在激光技术、通信和精密测量中有重要应用。
Optical Beat Frequency具体释义
Optical Beat Frequency的英文发音
例句
- A Measurement Method for a CW Laser Modulation Spectrum Based on Optical Beat Frequency(OBF)
- 一种基于光拍频(OBF)的连续激光调制光谱测量方法
- The theoretical equality of optical beat frequency and traditional interference phenomenon is performed, the result can be applied to varing beat frequency as well as to constant beat frequency, which provid a theoretical basis for detection of vibration using heterodyne laser probe.
- 从而在理论上统一了光拍频(OBF)与传统的干涉现象,这一结果对拍频为常量与拍频随时间变化两种情况均适用,由此可以给出用外差激光探针测振动的理论依据。
- So far, mostly, the research of optical beat frequency has concentrated on the use of single-frequency pulse generated by single longitudinal mode laser.
- 但迄今为止,关于光拍频(OBF)技术的研究主要集中在利用单纵模激光器所产生的单纵模脉冲上,而对于锁模激光器输出的ps锁模脉冲的研究还没有引起人们足够的重视。
- As the laser from LD incidents on the diffraction grating and ± 1 order diffraction beams are interfered, if the interferometer has the optical path difference, the optical beat frequency will appear. Measuring phase of beat signal, the displacement of grating will be obtained.
- 激光与光栅上衍射的±1级衍射波会合,由于有光程差而发生光拍频(OBF),测量拍频信号的相位移则可测得光栅的位移。
- Optical Beat Frequency(OBF) Measurement Technic and Its Application
- 光拍频(OBF)测试技术及其应用
