On the Treatment of Data Acquisition Sampling Frequency in Fiber Optic Sensor Controlling

The development of optical fiber sensor, digital signal processing and analysis technology makes the field of sensor technology and demand more popular and improved to some extent. Fiber optic sensor changing from extensive optical sensor signal power into the direction of depth, the signal carrier for optical time domain and frequency domain, the polarization of minor changes, as well as a variety of radiation-based conversion of all sensing have become the theory and application of vector, thus broadening the scope and sphere of application. Digital signal processing and analysis technology is the great leap forward of processing technology focusing on information technology, achieving the balance of software and hardware processing, realizing the parallel processing and separation, and implanting intelligent mode and function. This paper focuses on the problem of optical fiber sensor in the control of the data acquisition and sampling frequency during the digital processing to develop the device and sensor systems and effective distribution, and sets up hardware and software to achieve the desired results, in the fiber-optic sensor sphere process of "known by realization", which can be used as optical fiber sensing applications in different fields for reference.
