Technology

Optical MEMS.
Built for the asset.

CEKO combines microfabricated sensing structures with optical readout. The passive sensing point can be positioned close to the physics of interest while interrogation and system electronics remain outside the asset.

Principles

Three layers of the platform.

The platform combines MEMS structures, optical signal transport and external interrogation in one scalable measurement architecture.

Wafer-level MEMS

The sensing platform starts at wafer level, where optical MEMS structures are fabricated with scalability in mind.

Optical transduction

Physical change is translated into an optical response that can be transported without bringing conventional electronics into the sensing point.

System integration

The sensing technology integrates with multiplexing, optical interrogation and data systems to form a complete monitoring platform.

Architecture

From one platform to multiple sensing points.

Multiplexing allows several optical sensing points to be interrogated within one broader system architecture.

Explore the full measurement chain — from broadband light in the fiber to dashboard-ready sensor values.

The SDAS sends broadband light into the fiber, each connected sensor reflects its own narrow wavelength band, and the SDAS fits the reflected peaks to extract physical values such as temperature, vibration, force, or hydrogen.

Change physical conditions

These sliders change the physical influence acting on each connected sensor. Temperature, force, and hydrogen retain a visibly slower response than vibration, but have been accelerated here so changes remain easy to observe during a short website visit.

Move the sliders for connected sensors to change the physical influence.

Connect a sensor or use a preset to reveal the controls.

Optical spectrum

Each connected sensor occupies its own wavelength band. Physical influence shifts the reflected peak position, and the SDAS fits those peak positions before converting them into physical values.

Light response → wavelength fit → physical values

Process view

White pulses show broadband interrogation light leaving the SDAS and splitting toward each connected sensor. A brief ring marks the reflection at each sensor before the wavelength-coded return pulse travels back. The instrument display inside the SDAS then glows as the returned peaks are measured, fitted, and converted into the physical values shown on the dashboard and output traces.

Decoded measurements

These traces represent the sensor-specific values after the SDAS has fitted the optical peaks and mapped them into physical parameters.
