The Science Behind Our Solutions

How Our Technology Works

This section tells the story behind the tech — useful for anyone new to fiber optic sensing.

Why Fiber Optic Sensing?

One Fiber. Infinite Data Points. Zero Maintenance.

Traditional sensors measure individual points. Fiber optic sensing transforms the entire fiber cable into a continuous sensing system — delivering millions of data points along tens of kilometers.

The Future of Industrial Monitoring

Key Advantages

Distributed Sensing

Every meter behaves as a sensor

Long Range

Up to 50+ km monitoring

High Resolution

Detects changes as small as microstrains

Immune to EMI

Works in harsh industrial environments

Passive & Safe

No electrical components in field

24/7 Monitoring

Instant alarms, real-time analytics

The Science of Light Scattering

Understanding how we extract valuable data from ordinary optical fibers

1

Laser Pulse Transmission

A laser pulse is sent through an optical fiber, traveling along the entire length of the cable.

2

Light Scattering

As the pulse travels, tiny portions of light scatter backward (Rayleigh, Raman, Brillouin scattering).

3

Data Analysis

Each scattering mechanism carries unique information about the environment around the fiber.

Our Interrogators Analyze

Our interrogators analyze this scattered light to compute real-time measurements across the entire fiber length.

Acoustic Vibrations

(DAS)

Temperature Variations

(DTS)

Strain Changes

(DSS)

Pressure & Displacement

(Structural)

This allows continuous monitoring of assets without installing thousands of conventional sensors.
