How to train a machine to see 3-D in the dark – Phys.org

Researchers at the Australian National University (ANU) have developed a new way to create an almost perfect hologram in near darkness.
Optical holograms are a clever way of producing a 3-D image of an object. They have a number of usesfrom protecting our ID cards from forgery, to real-time imaging of living cells.
The new breakthrough will allow holograms to perform these vital functions and more with a lot less light.
According to Dr. Steve Lee, the quality of an optical hologram is often l…
