High-Temperature Sensor Based on 45° Tilted Fiber End Fabricated by Femtosecond Laser

Abstract

In this letter, we proposed and experimentally demonstrated a novel fiber sensing head based on 45° tilted fiber end for high-temperature measurement. The sensing head was fabricated by femtosecond laser using a line-scanning method. The light is mainly split into two beams at the 45° tilted fiber end, which forms a Michelson interference with a fringe… (More)
