To evaluate the dynamic characteristics of Micro-Gyroscope with small dimension and high vibration frequency
a new measurement setup based on the high speed camera armed with microscope and digital image technique was presented.The natural frequency
quality factor
first mode of fold beam and Young’s modulus of the double linear vibratory gyroscope were measured by the new setup. The experimental results show the sensitivity of this setup is up to 0.01 μm and relative errors in different driving frequencies are less than 0.023%.
