In this paper, dual-CCD to achieve a hollow cylinder of carbon thermal strain measurement. The use of high-precision dual-CCD imaging system for objects in the face of it, under the edge of image acquisition at the same time, recording at different temperatures around the edge of the digital image. Different temperatures on the number of images related to measurement, the objects can be generated as a result of temperature and strain. To obtain a stable number of images, measurement results obtained using the white-light digital speckle correlation method, algorithm, through the relevant objects in the plane as the movement of pixels, to obtain information on object deformation. To overcome the interference of external factors and the impact of system noise, it is necessary to take the average of many measurements of the methods to eliminate, which greatly improved the accuracy of the experiment
