Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 8:
9. A hybrid interferometer, comprising:
a first cavity mirror affixed to a frame;
a test mass physically coupled with the frame via one or more bridges such that the test mass is displaced along a sensing direction relative to the frame when the frame accelerates along the sensing direction;
a second cavity mirror affixed to the test mass and cooperating with the first cavity mirror to form a Fabry-Perot cavity with a cavity spacing that changes when the test mass is displaced relative to the frame along the sensing direction;
a reflector affixed to the frame; and
an atom interferometer configured to measure acceleration of the frame along the sensing direction using an optical beam that propagates along the sensing direction and is reflected by the reflector.
