Abstract

An embodiment of the present application provides a salinity measurement method. The method utilizes the characteristic that strain in an optical frequency domain reflectometer system causes changes in the collected signal. The method obtains the signal of a first optical fiber not immersed in a target area and the signal of the first optical fiber after immersion in the target area, and establishes a relationship between the signal change of the first optical fiber and the strain of the first optical fiber. Based on the correspondence between shape and salinity, a correspondence between the signal change and the salinity is then established. By obtaining the signal change of the first optical fiber at each position immersed in the area to be detected, the salinity of each position of the first optical fiber immersed in the area to be detected can be obtained. The signal change of the first optical fiber at each position immersed in the area to be detected can be obtained all at once, reducing the time spent on obtaining salinity and improving the efficiency of salinity detection.
