Paper Abstract

In order to characterize energetic materials, it is highly desirable to be able to measure velocity, position, pressure, and temperature throughout the event. This paper looks at approaches associated with extracting these parameters from data obtained using high speed fiber grating sensor systems. Prior work has demonstrated that velocity, position, and local pressure data may be obtained using chirped fiber grating sensors (CFBGs). Uniform fiber grating sensors have been used to quantify local pressures beyond the range associated with CFBGs. A main challenge faced today is the separate of these parameters from temperature. A novel approach that may be used to isolate temperature and pressure measurements using a high-speed fiber grating sensor system is presented in this paper.
