Micro-scale speckles with particle dispersion method are fabricated as the deformation carriers in the digital image correlation method. Micro-scale carbon particles are mixed with epoxy resin proportionally, followed by solidifying, centrifugal and spinning. In the end, a speckle film can be fabricated, which can be transferred to the surface of specimen. The quality of speckles is evaluated by the average gray gradient and the fabrication parameters including solidifying time, centrifuge speed, and spinning rate are studied and optimized.
