Four-channel rugged FBG interrogator built for aerospace and defence platforms, with onboard processing and storage and a wide operating temperature range.

The AGTR-NG4 is one of two current PhotonFirst aerospace interrogators. PhotonFirst states four optical channels, a 22 kHz sampling rate, an operating range of -45 C to +70 C, and validation against MIL-STD-704, MIL-STD-810 and MIL-STD-461. Data handling is done onboard by an integrated miniature single-board computer, with Ethernet/UDP/TCP-IP communication and an ARINC 801 optical interface. No wavelength range, resolution or mass figures are published on the open website.
