FIBRE OPTIC SENSOR

Turn a single optical fibre into a continuous sensor. OKI's fibre optic sensing detects vibration along the cable, identifies anomalies and pinpoints where they happened — across several tens of kilometres.

SILICON PHOTONICS

AN OPTICAL SENSOR THE SIZE OF A CHIP

In November 2024 OKI announced an ultracompact photonic integrated circuit built with silicon photonics — complex optical circuits fabricated onto a silicon substrate using semiconductor manufacturing methods. Instruments that previously needed individual optical fibre connections shrink to roughly smartphone dimensions, with the low power consumption of an LSI and the economics of mass production. It brings optical fibre sensors, laser vibrometers, optical biosensors and optical transceivers within reach of far more applications.

HOW IT WORKS

THE FIBRE IS THE SENSOR

Light travelling through an optical fibre changes subtly when the fibre is disturbed. OKI reads those changes to work out what happened, and where.
1
LIGHT TRAVELS THE FIBRE
A light signal is sent along a standard optical fibre. The cable runs the length of the area being monitored, with no sensors to install along the route.
2
VIBRATION CHANGES THE SIGNAL
When vibration reaches the fibre, the returning light fluctuates. OKI analyses the statistical characteristics of those fluctuations to separate normal conditions from abnormal ones.
3
ANOMALY AND LOCATION, INSTANTLY
Anomalies and their positions along the fibre are identified immediately — several at once, and without the cost and complexity of coherent detection.
APPLICATIONS

CRIME AND DISASTER PREVENTION, ACROSS WIDE AREAS

Security

  • Intruder detection at important facilities
  • Perimeter and boundary monitoring
  • Several anomalies detected simultaneously
  • Immediate alert, with the location along the fibre

Infrastructure

  • Maintenance monitoring of buried lifelines
  • Bridges, tunnels and slopes
  • Collective monitoring across several tens of kilometres
  • Wide-area coverage from a single fibre run
