Home / Fp Interferometric Fiber Optic Sensor
The Fabry-Perot (F-P) interferometric optical fiber sensor is one of the most widespread types of fiber-optic sensors, due to its properties of being versatile, simple, responsive, precise and immune to environmental noise [1, 2, 3]. Our Fabry-Pérot sensor operates by analyzing the Free Spectral Range (FSR), i.
The optical fiber serves solely as a light transmission medium and does not constitute the sensing element itself. Our Fabry-Pérot sensor operates by analyzing the Free Spectral Range (FSR), i.e. the
