Development of Temperature-Cancelled Pressure-Sensitive Paint System for Capturing Unsteady Motions

开发了一种温度取消压敏涂料（PSP）系统，用于捕获运动物体上的时间分辨表面压力。该系统基于Sakaue的动作捕捉PSP方法（青年科学家资助B， #21760660）。结果表明，两个具有相似温度依赖性的发光团的组合使系统能够消除或降低系统的温度依赖性。通过获取两幅发光图像并对其进行比值，消除或大大降低了温度依赖因子。利用钌配合物与荧光素的结合或铂卟啉与量子点的结合，所研制的系统实现了温度抵消压力测量。

A temperature-cancelled pressure-sensitive paint (PSP) system was developed to capture the time-resolved surface pressures on a moving object. The system was based on a motion-capturing PSP method by Sakaue (Grants-In-Aid for Young Scientists B, #21760660). It was shown that a combination of two luminophore with similar temperature dependencies enabled the system to cancel or reduce the temperature dependency of the system. By acquiring two luminescent images and ratio the two, the temperature dependent factor was cancelled or greatly reduced. It was found that the developed system showed a temperature-cancelled pressure measurement by using combination of ruthenium complex and fluorescein or a combination of platinum porphyrin and quantum dot.
