A Fabry–Perot sensor prototype for low-pressure measurements
in: Microwave and Optical Technology Letters (2014)
An interferometric Fabry–Perot cavity based on hollowcore ring photonic crystal fiber combined with a silicone diaphragm is proposed for low pressure sensing. The sensor exhibits a sensitivity of 0.086 nm/mmHg for a pressure range between 0 and 337.5 mmHg.These values are in the range of physiological pressures, such as intravascular pressure.
