Author Affiliations +
Plenoptic imaging (PI) is an optical technique to perform three-dimensional imaging in a single shot. It is enabled by the simultaneous measurement of both the location and the propagation direction of light in a given scene. Despite being very useful for extending the depth of field, such technique entails a strong trade- off between spatial and angular resolution. This makes the resolution and the maximum achievable depth of focus inversely proportional; hence, resolution cannot be diffraction-limited. We have recently proposed a new procedure, called Correlation Plenoptic Imaging (CPI), to overcome such fundamental limits by collecting plenoptic information through intensity correlation measurement. Using two correlated beams, from either a chaotic or an entangled photon source, we perform imaging in one arm and simultaneously obtain the angular information in the other arm. In this paper, we discuss the case in which the two correlated beams of light are generated by spontaneous parametric down-conversion. We review the principles of CPI with entangled photons and discuss its resolution and depth-of-field limits.
