A novel demodulation scheme for a point-type fiber sensor is designed salinity concentration monitoring based on Sagnac interferometer (SI) composed of tapered polarization-maintaining (TPMF) and optical time stretching technology. The SI, constructed using PMF with taper region 5.92 μm an overall length 30 cm, demonstrated notable enhancement in the evanescent field, which intensifies interaction between light field external salinity. This allows direct assessment changes by analyzing variations SI reflection spectra experimental results indicate that sensitivity 0.151 nm/‱. In contrast to traditional optic sensors depend spectral slower response rates, this work introduces new approach where shift translated domain, utilizing dispersion compensation (DCF) rate reaching up 50 MHz. outcomes reveal exhibits -0.15 ns/‱ domain. anticipated play pivotal role remote, real-time ocean
