Abstract：

According　to　the　principle　of　blackbody　radiation,　the　experimental　exploration　of　high　temperature　optical　fiber　temperature　sensor　was　carried　out.　The　high　temperature　resistant　calcium　tungstate　material　was　used　as　the　blackbody　radiation　material　to　be　made　the　optical　fiber　radiation　probe.　Optical　power　meter　was　used　to　measure　the　optical　power　of　980nm　wavelength　in　every　10°C　in　the　range　of　150-800°C.　The　fourth-order　polynomial　was　used　to　fit　the　relationship　between　the　radiation　optical　power　and　the　temperature,　and　the　fourth-order　optical　power　and　temperature　expression　with　a　fitting　degree　of　0.99953　was　obtained.　The　temperature　measurement　accuracy　was　within　1　%　in　the　temperature　range　of　400-800　℃.　©　2024　SPIE.
