Distributed Sensing System (DSS)


Luna Technologies

Luna Technologies' Distributed Sensing System (DSS™) 4300 is a fiber optic sensing tool for making temperature and strain sensing measurements. The DSS™ uses swept-wavelength interferometry to simultaneously interrogate thousands of fiber optic sensors in a single fiber. These sensors consist of discrete Fiber Bragg Gratings (FBG) which can each reflect the same nominal wavelength. As such, the sensors can be quickly and economically fabricated on the draw tower, eliminating the need for individual grating fabrication. The DSS™ 4300 combined with Luna's sensing fiber provides a tool for distributed fiber sensing with up to 1 cm spatial resolution along the length of the fiber. Applications supported by the DSS™ include shape sensing, temperature and strain profile characterization and structural monitoring for naval, aerospace and civil applications.
