Fibre-optic measurement Scaime
Geometrical parameter analysis of the high sensitivity ﬁber optic angular displacement sensor Fiber optic angular displacement sensors have been designed for applications that require the measure-ment of very small angular displacements (in the order of 1 µrad or less). By measuring the angular displacement, other physical quantities can be indi-rectly measured or detected, as pressure...

Geometrical parameter analysis of the high sensitivity
1408 IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT, VOL. 60, NO. 4, APRIL 2011 Modeling of Light Intensity-Modulated Fiber-Optic Displacement Sensors Panagiotis Polygerinos, Lakmal D. Seneviratne, Member, IEEE, and Kaspar Althoefer... A novel low cost interferometric displacement sensor has been developed which tracks distance from the tip of a fiber optic probe. A unique interrogation technique is used which produces a 32-bit phase word, giving the system a dynamic range greater than 10 9.
