The fastest imaging system ever devised has been demonstrated by researchers reporting in the journal Nature.
Their camera snaps images less than a half a billionth of a second long, capturing over six million of them in a second continuously.

The approach will be instrumental in analysing, for example, flowing blood samples in a search for diseased cells.
What is more, the camera works with just one detector, rather than the millions in a typical digital camera.
