Micron Optics, Inc., the leading provider of innovative equipment for fiber optic sensing equipment, today announces the launch of the os7510 and os7520 Fabry-Perot Accelerometers. This patented design brings a fresh approach to the fiber-based accelerometers on the market today and addresses the shortcomings of previous designs.

Based on Fabry-Perot (FP) technology, the os7500 is the first of its kind due to the unmatched sensitivity, ultra-small footprint providing ease of installation in most applications, and patented design that allows for os7500s to be deployed in series on a single optical fiber. The os7500 is also compatible, from a system level, with Fiber Bragg Grating based strain and temperature sensors, thereby enabling comprehensive fiber-based sensing networks. This is important to customers monitoring civil structures as well as security applications as optical sensors are immune to EMI, corrosion, and are inherently passive devices. Those features, along with the fact that optical sensors require no calibration, mean no routine maintenance or annual replacement of sensors as conventional electrical gages commonly require.
The os7500 series of optical accelerometers are available in two configurations; the os7510 is optimized for long-term civil infrastructure measurements and the os7520 is designed for lower frequency range, near seismic events. These sensors can be daisy chained on a single HYPERION channel, which allows for these sensors to be integrated into systems with strain, displacement, temperature, etc. measurements.
