Abstract

Embodiments relate to an optical sensor for sensing hydrogen gas, which includes an optical fiber through which light moves; a ferrule formed at one end of the optical fiber to surround the optical fiber; and a sensor module configured to form an interference wave according to a Fabry-Perot interferometer with respect to light that moves through the optical fiber, wherein the sensor module includes a sensing material that expands and contracts by reacting with hydrogen gas, and spectrum periodicity of the interference wave changes according to a volume change of the sensing material, and a hydrogen gas detection system including the optical sensor.
