Description
The si155 is an industrial grade fan-less optical sensing interrogator. Featuring both static and dynamic full spectrum analysis, the si155 provides long-term, reliable and accurate measurements of hundreds of sensors on 4 parallel, 160 nm wide channels.
The si155 features a high power, low-noise, ultra-wide swept wavelength laser with guaranteed absolute accuracy on every scan which is realized with Luna's patented Fiber Fabry-Perot filter and wavelength reference technology.
The HYPERION platform, on which the si155 is based, features groundbreaking capabilities including high-performance DSP and real-time FPGA processing on-board. This enables rapid, full-spectrum data acquisition and flexible peak detect algorithms of Fiber Bragg Gratings (FBG), Long Period gratings, Fabry-Perot (FP) and Mach-Zehnder (MZ) sensors with low latency access to data for closed-loop feedback applications.
The HYPERION platform is now compatible with ENLIGHT, Sensing Analysis Software, which provides a single suite of tools for data acquisition, computation, and analysis of optical sensor networks, see http://www.micronoptics.com/products/sensingsolutions/software/ for more information. The HYPERION platform also includes a comprehensive Application Programming Interface (API) and examples written in LabVIEW, Python, Matlab, C++ and C#.
