Abstract

This paper proposed a method to measure the displacement of micromechanical components moving on the focal plane of optical microscopy. This method is based on the interferometric analysis using the laser system and the grating fabricated on the micromechanical components. The advantage of this method is its high measurement speed, accuracy and the simplicity of the configuration. We demonstrated to measure the displacement of oscillatory body at the speed of 50 kHz and within the noise of 35 nm. This method will be a promising option to measure and control the translational motion of the micromechanical devices at high frequency domain.
