Novel High Speed Fiber-Optic Pressure Sensor Systems

This project would develop and improve a new class of high-speed pressure transducers that would allow for high pressure and high speed events to be accurately monitored. A major effort is the reduction of cost to allow pressure readings in critical applications such as automobile airbag deployment, engine combustion monitoring, wind-pressure loading, road and bridge load recording and traffic flow control. Applications in the defense sector such as gun barrel life monitoring and aerodynamic pressures on airplanes could potentially be drastically improved. This sensor technology can potentially revolutionize the way pressures in engineering systems are monitored, in definition, fidelity and how much those systems cost. These new sensors are fiber-optic and constructed of non-metallic synthetics which alleviate the inherent electrical interference and corrosion problems associated with the current metallic electrical systems. The nature of this technology incorporates a thin diaphragm design coupled with an optical demodulation scheme which provides a very fast response time. The compact construction also allows for high spatial resolution in applications, providing a vastly more complete data set than is currently possible. Preliminary tests have shown linearity with a correlation coefficient of .9999 as well as a hysteresis of less than 0.3% and demonstrated rise time of less than 2μs from 0 kPa to 140 kPa. The goal of this project is to develop a complete test of this technology for high-speed, high-accuracy applications, specifically cost-effective data acquisition techniques and practical mounting methods tailored for the subject environment. The secondary goal is to develop improvements to increase pressure capabilities to 500 MPa suggest manufacturing methods for sensor production. The testing will center on the high-speed and high pressure end of the performance envelope as this would provide information that is also useful for the slower and lower pressure applications. This work was split out of the CTME High Strain Rate Proposal when Picatinny Arsenal came forward with the connection to Dr. Xingwei Wang's (UMass-Lowell) work on this new fiber-optic pressure sensor technology just after the original white paper was submitted. Picatinny Arsenal would commit additional money (not used for match) for this effort to augment this effort and help facilitate the work with UMass-Lowell through Picatinny. This can present a significant leverage opportunity for CTME money on an emerging technology that has the possibility for wide-ranging impact on transportation systems in areas of safety, efficiency, performance and life monitoring.
