New Optical Fiber Infrasound Sensor deployment at Camp Elliot
Optical Fiber Infrasound Sensors (OFIS) are long compliant tubes
wrapped with two optical fibers that interferometrically measure
atmospheric pressure along the length of the tube. The UCSD OFIS
team is building a multi-arm OFIS array at the Camp Elliot field
station. The proposal is to test this OFIS array with the back
azimuth determination software in a real-time setting by tracking
the airplanes that take off and land at the nearby Miramar Naval
Air Station. Also proposed is the development of an infrasound
source, using an array of low-frequency speakers, and testing this
system as an OFIS calibration tool. The system is dependent on
HPWREN to for remote operation and data transfer throughout this
research.
