For measurements of all types, including shape, strain, temperature, liquid level, and more
Innovators at NASA’s Dryden Flight Research Center have developed an innovative data acquisition method that enhances strain measuring in a wide range of applications. The technology is a multiplexing method for interrogating multiple optical fibers on a single data channel of an optical frequency-domain reflectrometry (OFDR) system. Rather than being limited to a single length of fiber per channel, the multiplexing system enables multiple shorter fibers to be addressed by a single channel. The system is compact and cost-efficient, since requiring fewer channels translates into reduced capital expense and smaller size. Furthermore, unlike current systems, which are limited by the number of channels available in the acquisition hardware, Dryden’s innovation extends the system’s flexibility without consuming additional channel resources.
The multiplexing capability is potentially useful for any application utilizing fiber optic strain sensors, including:
Dryden has applied for patent protection for this technology.
This technology is part of NASA’s technology transfer program. The program seeks to stimulate broad commercial use/application of NASA-developed technologies. NASA is flexible in its agreements, and opportunities exist for licensing and joint development. Dryden is interested in a partnership to commercialize this technology.
