Paper Abstract

A non-contact optical approach to measure the in-plane displacement of an object is introduced in this paper. Through a ste of optical system, the image of the object to be measured is formed in the image plane of the CCD. When the object moves in-plane, its image moves in the image plane of the CCD accordingly. Consequently, the displacement of the object can be detected in real-time by measuring the movement of its image with CCD. The prosed w\system is suitable for non-contact measurement such as deformation of objects in high temperature, deformation of elastic objects and low frequency mechanical vibration. It can be widely used in mechanics experiments to achieve high precision measurement in long working distance.
