Research Abstract

感圧塗料 (PSP) と感温塗料 (TSP) の両技術を複合させ,圧力・温度場の同時計測を通じてPSPの有する温度感度の補正を行う手法である複層PSP/TSP (DL-PTSP) について,DL-PTSP を構成するPSP層とTSP層の温度差を低減するとともに,両層の温度差の影響を内包した温度補正手法を提案することで,PSPの温度補正の高精度化を通じた圧力計測精度の向上を実現する.さらに,特に温度変動の幅が大きくこれまでPSPの適用が困難であった条件下へのPSPの適用可能性を拡大するため,低温度感度PSPの実現および本手法のDL-PTSP手法との複合化に取り組む.
