Abstract

This study aims to optimize the structure of gold-sputtered U-shaped plastic fiber sensors.Design/methodology/approachA group of U-shaped Au-sputtered plastic optical fiber sensing probes with polishing angles of 45°, 90° and 135° is prepared.FindingsThe experimental results show that the spectral response and sensitivity of the sensor at 45°polishing angle is twice that of the sensor at 90°.Research limitations/implicationsDue to the limitations of laboratory temperature and equipment, the overall effect has not reached the ideal, but the expected effect has been obvious. Experiments also optimize the sensor.Practical implicationsOptical fiber sensing has always been an indispensable part of various fields.Social implicationsSensor optimization is of great help to the progress of technology and the development of science and technology.Originality/valueThe authors have no conflicts of interest to disclose.
