ABSTRACT:
An optical displacement sensor is disclosed comprising a beam splitter having two optically coupled and mechanically coupled optically resonant cavities. The respective cavity lengths of the optically resonant cavities are functions of an environmental stimulus. By virtue of the optically coupled optically resonant cavities, the output of the beam splitter is less sensitive to input wavelength variation yet retains high sensitivity to the environmental stimulus.
