FBG Interrogators
PhotonFirst's PIC-based Fiber Bragg Grating interrogation systems, ranging from the compact single-channel GTR to DO-160G qualified aerospace units and a custom-only technology platform.
Single-channel, PIC-based FBG interrogator for compact quasi-distributed fibre optic sensing installations. Reads up to eight Fiber Bragg Grating sensors on one optical fibre.
Eight-channel PIC-based FBG interrogator for multiplexed strain and temperature sensing. Supports up to eight FBG sensors per optical channel.
Four-channel rugged FBG interrogator built for aerospace and defence platforms, with onboard processing and storage and a wide operating temperature range.
Eight-channel DO-160G qualified FBG interrogator optimised for dynamic measurement, using sequential channel sampling.
A programmable FBG interrogation technology platform that PhotonFirst offers only as the basis for custom developments, not as an off-the-shelf product.
A PhotonFirst product for which a datasheet download page exists on photonfirst.com, but which is not described or linked anywhere in the site's current product navigation.
