Optical Accelerometer

Luna’s os7200 are fiber Bragg grating (FBG) based accelerometers, featuring a wide range of sensitivities and frequency responses, which can be dispersed over 10’s of kilometers and integrated with ease into monitoring solutions.

Product Description

The os7200 features a fresh new approach to vibration monitoring by utilizing FBG technology to measure a wide range of vibration events, all while being able to pair with various physical parameters e.g. strain, temperature, displacement, pressure, tilt.


Installation is simple and repeatable with standard threaded connections and is available in one, two or three axis configurations. A rugged, sealed metallic body, and Kevlar ™ armored cables enable deployments in austere environments. Up to 128 os7200 sensors can be integrated on Luna’s HYPERION platform for reduced total system costs.


The os7200 series of sensors is compatible with ENLIGHT Sensing Analysis Software, which provides an integrated suite of tools for data acquisition, computation and analysis of optical sensor networks as well as the HYPERION platforms comprehensive Application Programming Interface (API) and examples written in LabVIEW, Python, Matlab, C++ and C#.
