We report on a novel kind of accelerating beams that follow parabolic paths in free space. This accelerating peculiar polygon beam (APPB) not only exhibits autofocusing property, but also possesses two types of accelerating intensity maxima, i.e., th

Difficulties often arise for digital image correlation (DIC) technique when serious de-correlation occurs between the reference image and the deformed image due to large deformation. An updating reference image scheme could be employed to deal with l

A transmission tower is a form of highly indeterminate space structures used extensively. A non-contact optical deformation measurement method is proposed for monitoring the deformation of transmission tower during loading test, which could not be ac
