Abstract

Recently, micro gyroscope sensors are adopted in handy camcorders to compensate external shock or vibration such as hand shakes. In developing micro gyroscope sensors, vibration analysis is inevitable but not easy since the micro gyroscope sensors are too small. In this paper, non-contact full-field ESPI (Electronic speckle pattern interferometry) measurement technique is introduced in vibration analysis of micro gyroscope sensors. Resonant frequencies and ODS(Operational deflection shapes) are measured and compared to each other. It is found that structure and PCB molding mass is one of most sensitive factors in designing micro gyroscope sensors.
