Abstract
The paper presents an optical-fiber hydrogen sensor. The
sensor utilizes a layered sensing structure. This structure is a layered
Fabry-Perot interferometer and includes gasochromic vanadium pentoxide
(V2O5). A structure is made at the end of multi-mode optical fiber
as a sensing element. The sensor permits to detect and to measure the
concentration of hydrogen in a gaseous medium. The optical H2 gas
sensor has a very short response time and a fast regeneration time at room
temperature.
