Fiber LDA System,nation of vector components of a moving object in the physical science. Among the variety of methods to measure the velocity, it is desirable to detect velocity without disturbing the motion of the moving object. An optical beam aiming at a moving object is supposed to be the best fit for this kindindenture 发表于 2025-3-30 19:34:06

Thermodynamic Limitations to the Measurement of Phase Shifts in Optical Fibers,e variations, the optical path length of a single mode fiber has a perfectly well defined value. This is not strictly true. At any temperature above absolute zero, there will be statistical fluctuations of all the physical properties, including the optical path length, and this will set a lover limiaviator 发表于 2025-3-31 05:11:56
