Quasi noise-free digital holography

Noise originating from the coherent nature of laser light is the scourge of digital holography, reducing the quality of holographic images below that of conventional photographs. Now, Pasquale Memmolo of ISASI-CNR and collaborators ...

Fragment tracking—insights into what happens in explosions

A bang and a swirl of dust from detonating 9 pounds of plastic explosive in the desert signaled the beginning of tests that—thanks to advances in high-speed cameras, imaging techniques and computer modeling—will help ...

The long-term impacts of studying cornea biomechanics

Nature has had millennia to optimize biomaterials for useful properties, from lightweight strength to walking on smooth, vertical surfaces. Mother-of-pearl, spider silk, cholla wood "skeletons" and gecko feet are all good ...
