By passing light from the palimpsest through a filter made up of liquid crystals, the researchers can adjust the wavelengths of the pictures that result by 10 billionths of a metre at a time.
The more that the light passing through the sample is slowed down, however, the more the two beams will be out of phase.
Light passing through each microlens focuses at a point a few tenths of a millimetre beyond it, and thereafter spreads out as a cone.
It could yield a light passing shower during the day, but it's a very low chance for this, so I'm expecting it to remain dry.
The mask is designed so that light passing through its thickest region is slowed by exactly two cycles compared with that passing through its thinnest.

Unlike conventional cameras, our femto camera captures an image as one thin slice at a time of one-dimensional space using a "streak tube, " a laboratory instrument that is commonly used by chemists to study light passing through chemical samples.
Light particles passing through the void would be expected to lose a little more energy than those passing through space cluttered with matter - if dark energy is stretching the Universe apart at a faster and faster rate.

With help from signals from roadside markers and traffic lights, in-car computers will be able to determine if a car should slam on the brakes, alert the driver to a passing vehicle in the blind spot or slow for a red light up ahead that another driver isn't heeding.
