It provides a general and simple miniature sensor design with referencing directiveness against system power fluctuations. The concept is demonstrated for a reflective-type displacement sensing cavity, and its potential for simultaneous measurand and temperature evaluation is evaluated.engGratingsDisplacement measurementOptical fiber transducersjournal article10.1049/el:19950244
