Enhanced digital gradient sensing using backlight digital speckle target

Digital gradient sensing (DGS) is a non-contact and full-field optical measurement technique, which assesses mechanical behaviors of transparent materials or specular structures by measuring angular deflections of light rays. However, owing to the …

Fluorescent digital image correlation applied for macroscale deformation measurement

Fluorescent digital image correlation (DIC) has been implemented on monocular and binocular fluorescence microscopes for shape and deformation measurements at the microscale and even the nanoscale by tracking fluorescent particles. This technique, …
