Abstract
An optical carrier based microwave interferometry (OCMI) system for measuring a physical, chemical, or biological property broadly comprises an optical carrier signal source, a waveguide, a microwave envelope signal source, a microwave modulator, an optical interferometer, a detector, and an analyzer. An optical carrier signal is modulated with a microwave envelope signal and transmitted through an optical interferometer. The optical signal is interrogated in microwave domain to obtain interference patterns or absorption/emission spectra corresponding to the physical, chemical, or biological property being measured.
