Quantum Imaging Method Doesn’t Need Light to Touch Object
TYROL, Austria, and VIENNA, Aug. 29, 2014 — A new quantum imaging technique can acquire an image of an object without ever detecting the light used to illuminate it.
Typically, to obtain an image of an object it must be illuminated with a light beam and a camera used to sense the light that is either scattered or transmitted through that object. However, a model light for such illumination is one for which cameras do not exist.
The new method, based on induced coherence without induced emission, was developed by...
