High-resolution distributed temperature sensing using a plastic optical fiber

Caption

This figure illustrates the result of distributed temperature sensing using a perfluorinated graded-index plastic optical fiber (POF). The top diagram shows the structure of the sensing POF, including a 7.0-centimeter cooled section. The lower plot presents the measured Brillouin frequency shift distribution along the POF, clearly indicating the temperature change in the cooled region.
