camera-takes-pictures-in-the-dark

Using a multi-step process a three-dimensional image can be obtain by removing noise from a laser scan made by detecting a single photon for each pixel.

This camera take pictures in the dark, single particles of light are recorded on each pixel of a solid-state detector, the computing technique takes a bare minimum number of photons reflected by a dimly lit object to stitch them together in order to obtain a 3D image.
