Abstract :
A hybrid micromachined-optoelectronic mechanical system (MOEMS) gyroscope is proposed. It consists of an electrically excited micro-mechanical resonator and an optical readout performed by a laser diode operating as an injection interferometer. An analysis of the system, validated by preliminary experimental results, indicates an attainable performance of 1 deg/h√Hz
