Based on the newLight® technology, FS61DSP Displacement Sensor is a ruggedized Fiber Bragg Grating (FBG) sensor designed to measure linear displacement on different types of structures. The sensor uses two FBGs in a push-pull configuration for effective temperature compensation. The linear tuning sensitive structure of isosceles triangle-shaped cantilever beam is designed which can be used to eliminate the influence from environmental temperature. ), FBG demodulators (FBG Interrogators), and application experience of the above products in different industries. For the current fiber grating displacement sensor range is small and the sensor can't display the displacement value on the spot, a large range of self-displaying fiber grating displacement sensor is proposed, through all levels of the transmission mechanism in the sensor, converting the amount of. The device consists of a pair of FBGs with different central wavelengths fabricated by femtosecond laser phase mask method and a metal substrate with lever structure.
