Our Technology
Fiber Optics + Advanced Interrogation Systems + Intelligent Analytics
Folium Sensing builds next-generation distributed fiber optic sensing systems designed to monitor large infrastructures with unprecedented accuracy. Our solutions combine optical physics, precision hardware, and intelligent analytics to deliver real-time measurements of strain, temperature, acoustics, and pressure over tens of kilometers. This page explains how our core technologies work and why they are transforming industrial sensing.
Distributed Fiber Optic Sensing (DFOS)
Turning ordinary optical fibers into intelligent sensor arrays
Distributed Fiber Optic Sensing uses laser light to measure physical changes along the entire length of an optical fiber. A single fiber acts as thousands of sensors, offering:
Why It Matters
DFOS eliminates the need for traditional point sensors and enables complete visibility of large or inaccessible assets.
How Fiber Optic Sensing Works
Physics Behind the Technology
Inside the fiber, a laser pulse experiences interaction with the glass material. Different scattering effects give rise to powerful sensing capabilities:
Rayleigh Scattering
Used for DAS (Distributed Acoustic Sensing)
Raman Scattering
Used for DTS (Distributed Temperature Sensing)
Brillouin Scattering
Used for DSS (Distributed Strain Sensing)
This combination of optical phenomena forms the backbone of Folium Sensing's products.
Advanced Interrogation Units
