Simultaneous interrogation of interferometric and Bragg grating sensors.
We propose a new method for the simultaneous interrogation of conventional two-beam interferometers and Bragg grating sensors. The technique employs an unbalanced Mach-Zehnder interferometer illuminated by a single low-coherence source, which acts as a wavelength-tunable source for the grating and as a path-matched f ilter for the Fizeau interferometer, thus providing a high phase resolution ou...
متن کاملInterrogation of interferometric sensors with a tilted fiber Bragg grating.
This paper describes the interrogation of interferometer-based transducers with a technique that involves the use of a tilted fiber Bragg grating. The interrogation process will be analyzed both from the conceptual and experimental points of view. Simultaneous interrogation of multiplexed interferometric transducers is successfully checked using this technique.
متن کاملDigital Demodulation of Interferometric Signals
The marriage of optical sensing techniques with sophisticated digital signal processing has resulted in a myriad of practical metrology systems. Optical metrology systems offer many attractive measurement features. These systems are inherently non-contacting, nondestructive, and immune from electromagnetic interference. In addition, since light is used as the sensing probe, the measurement syst...
