A spinning object in our neighborhood of the galaxy is beaming powerful radio waves at Earth — and astronomers don't know what it is. The object is smaller than the sun and it must be spinning, ...

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 ...
