Aerospace multichannel FBG interrogator

Fiber sensing in Aerospace becomes reality with Integrated Photonics

Full solid state, multi-channel, fiber sensing versatility, fitting into a miniature turnkey solution.

The AeroGator demonstrates great versatility, providing channel multiplexing with 8 sensors per fiber, high resolution sensing, high sampling speeds per channel and programmable multiplexing profiles. With its small dimensions, its low weight and low power consumption, the AeroGator is by far the smallest footprint multi-channel FBG interrogator currently available and particular suitable for aerospace applications.
