Optical fiber for distributed temperature sensing (DTS)
DSS 4300 LUNA Innovations

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