The x25 interroga- tor core employs full spectral scanning and data acquisition, providing measurements with high absolute accuracy, flexible software post-processing, and high dynamic range performance. x25 based interrogators support continuous on-board NIST traceable wavelength reference components and are ideally suited to measure many different optical sensor types, including FBGs, long period gratings, extrinsic Fabry-Perot sensors, and many others. Well over half of the fiber optic sensors deployed today are mea- sured with instrumentation that uses Micron Optics technology. The Micron Optics "sm - Sensing Module" platform responds directly to the user com- mands of the optical interrogator core and outputs sensor wavelength data via Ethernet port and custom protocol. All module settings, sensor calculations, data visualization, storage, and alarming tasks are run on an external PC or sensor processor module The Sensing Module platform is ideal for custom, client developed system manage- ment tools, but is equally compatible with local or remote installations of Micron Optics Micron Optics ENLIGHT Sensing Analysis Software is included with Micron Optics sensing interrogator systems and provides a single suite of tools for data acquisition, computation, and analysis of optical sensor networks. ENLIGHT combines the usefu features of traditional sensor software with the specific tools needed to optimize opti- cal properties during the design, implementation, and operations phases of an optical sensor system. Tables, graphs, and additional data visualization features make ENLIGHT easy to use.
