Pm. Cavaleiro et al., REFERENCING TECHNIQUE FOR INTENSITY-BASED SENSORS USING FIBER OPTIC BRAGG GRATINGS, Electronics Letters, 31(5), 1995, pp. 392-394
An all-optical fibre referencing scheme for intensity based sensors wh
ich uses two identical fibre Bragg gratings is described. It provides
a general and simple miniature sensor design with referencing effectiv
eness against system power fluctuations. The concept is demonstrated f
or a reflective-type displacement sensing cavity, and its potential fo
r simultaneous measurand and temperature evaluation is evaluated.
