Datasheet

Overview

The Luna HYPERION si255 is an industrial-grade, fan-less optical sensing interrogator for high-speed multipoint fiber optic sensing. It performs both static and dynamic full-spectrum analysis and measures nearly 1000 sensors on up to 16 parallel, 160 nm wide channels.

The instrument uses a high power, low noise, wide swept wavelength laser with guaranteed absolute accuracy on every scan. This is achieved with the Micron Optics patented Fiber Fabry-Perot filter and wavelength reference technology. Each data set is calibrated and verified against a NIST traceable reference.

The HYPERION platform includes on-board DSP and real-time FPGA processing. This allows rapid full-spectrum data acquisition and flexible peak detection for Fiber Bragg Gratings (FBG), Long Period Gratings (LPG), Fabry-Perot (FP) and Mach-Zehnder (MZ) sensors, with low-latency access to data for closed loop feedback applications.

Models and software

The si255 comes in Standard, High Speed and Enhanced Visibility models, and each one is available with a depolarized source. The platform works with ENLIGHT Sensing Analysis Software for data acquisition, computation and analysis of optical sensor networks. It also includes an Application Programming Interface (API) with examples in LabVIEW, Python, MATLAB, C++ and C#.
