Optical Sensing Instrument | si255 Description The si255 is an industrial grade fan-less optical sensing interrogator. Featuring both static and dynamic full spectrum analysis, the si255 provides long-term, reliable and accurate measurements of nearly 1000 sensors on 16 parallel, 160 nm wide channels. Full spectrum at 1 kHz with 160 nm on 16 parallel channels simultaneously, eliminating the need for optical switches The si255 features an all new, high power, low noise, ultra wide swept wavelength laser with guaranteed absolute accuracy on every scan which is realized with Micron Optics patented Fiber Fabry-Perot lter and wavelength reference technology. The all new HYPERION platform, on which the si255 is based, features new and groundbreaking capabilities including high-performance on-board DSP and real-time FPGA processing. This enables rapid full-spectrum data acquisition and exible peak detect algorithms of Fiber Bragg Gratings (FBG), Long Period FBGs and Fabry-Perot (FP) sensors with low-latency access to data for closed loop feedback applications. Dynamic and absolute measurements of FBGs, LPGs and FP optical sensors from detailed optical spectrum Single and continuous 26 dB dynamic range, available to each sensor on each channel, independent of differential system losses Data verication key guarantees only valid output. Each data set is calibrated and veried against any potential sources of system error (coming soon). Proven reliability and longevity of the Micron Optics swept wavelength source, with over 100 million hours logged since 2000 Dynamic and absolute measurements of FBG and FP sensors on 16 parallel, 160 nm wide channels The HYPERION platform includes a comprehensive fully supported Application Programing Interface (API) and LabVIEW, Python, Matlab, and C++ examples. Micron Optics ENLIGHT Sensing Analysis Software which provides a single suite of tools for data acquisition, computation, and analysis of optical sensor networks is coming soon. More information on ENLIGHT can be found here.
