Shrink the Star Trek tractor beam down to a microscopic scale, add the ability to twirl the objects trapped in its path, and you’d have a system much like the one described in the 4 May issue of the ...

To demonstrate the system, the researchers showed that it could reconstruct real-time high-quality still images of a model jet engine rotating at about ∼2170 rpm (top images) and a CPU cooling fan ...

In the Optica Publishing Group journal Optics Letters, researchers presented their innovative imaging system based on a single-pixel detector. They demonstrate that it can capture images of an object ...

Objects rotating at high speed are a feature of modern engineering in various fields, and online inspection of them is a critical challenge. A project at China's Jinan University has now developed a ...
