報告摘要：

As the most active and outstanding non-contact, full-field optical technique, digital image correlation (DIC) has been widely used in scientific research and industrial fields due to its simple optical setup, low environmental vulnerability, wide measuring range and the ability to measure more physical quantities. By tacking the randomly distributed speckle, DIC can obtain information of the tracked object and further calculated its full-field deformation. Thus, speckle is the basis factor of DIC, which will affect the measuring accuracy, computational efficiency, and stabilities of DIC results. Therefore, the comprehensive evaluation of speckle quality, design and optimization of the digital speckle pattern (DSP), and fabrication of optimized DSP will contribute to the standardization of DIC, in details, will reduce computational errors, improve the computational efficiency and enhance the stability of DIC measurements. In order to realize the standardization of DIC, this lecture is devoted to the optimization design and fabrication of the DSPs.
