Abstract
An object that might be at least partially obscured is imaged. Frequency-entangled photons are generated. The frequency-entangled photons include photons having first and second frequencies. Those photons having the first frequency can pass through the obscuration and illuminate the object. Photons scattered by the object and those photons having the second frequency are used to form an image by considering coincidences in time of arrival.
