Optical Pressure Sensors | The Design Engineer's Guide - Avnet
WEBFibre-optic pressure sensors can be classified as either extrinsic, where the sensing takes place outside the fibre, or intrinsic, where the fibre itself changes in response to pressure. Very sensitive optical measurements can be made by exploiting interferometry: measuring the change of phase between light that has taken two different paths.
