Research Of Doppler Fiber Velocity Interferometer

This article is based on the project's requirements and technical indicators and the principle of Doppler fiber velocimetry as a reference, to design the Doppler fiber velocity interferometer with the unique advantage. It's unique is that:at the same time can achieve multi-point monitoring, high-speed impact of a one-time monitoring, but also for low-speed measurements. Make detailed description of DC receive part and data processing part of the interferometer system. Through the buzzer, vibrator, intense laser flyer, three practical measurement systems to verify the utility and scope of application of the Doppler optical fiber interferometer. In addition, analyze the noise of the experimental system and make corresponding improvements.
