Method and device for on-line detection of salinity of seater
The present invention provides a method and device for on-line detection of the salinity of seawater. A sweep frequency synchronous signal controls a sweep frequency laser light source such that the wavelength of a frequency modulation light wave output by the sweep frequency laser light source is a periodic saw-tooth wave signal. The frequency modulation light wave is divided into two beams, respectively transmitted to a refractive index probe and a temperature probe in seawater. The refractive index probe is an interference instrument structure, and the frequency value of an interference light intensity signal fed back by the refractive index probe is related to the refractive index of seawater. The refractive index of seawater is calculated by performing discrete Fourier transformation on the interference light intensity signal. The temperature probe is internally provided with a fiber Bragg grating, and the Bragg wavelength of the reflection spectrum of the temperature probe is related to the temperature of the seawater. The sweep frequency synchronous signal and the reflection light intensity signal of the fiber Bragg grating are subjected to synchronous discrete sampling, and the temperature value of the seawater is calculated according to a grating temperature sensor demodulation algorithm. The salinity value of the detected seawater is obtained by solving an empirical equation according to the obtained refractive index, the temperature value and the average wavelength of the frequency modulation light wave, thereby implementing on-line detection of the salinity of seawater.
