The deformation measurement technology based on differential fiber interferometer with PCI data acquisition system

摘要：

　　A deformation measurement technology for barrel in the launch based on differential fiber interferometer was supposed.The PCI data acquisition system and phase demodulation algorithm was used to replace the traditional hardware phase demodulation circuit which simplifying the structure and avoid the edge distortion of phase demodulation device.Experiments were done to measure the deformation of the barrel in the launch by this system.The results show that it had good response characteristics and is suitable for the transient deformation measurement of the barrel in the launch.
