  The correlation properties of light provide an outstanding tool to overcome
the limitations of traditional imaging techniques. A relevant case is
represented by correlation plenoptic imaging (CPI), a quantum-inspired
volumetric imaging protocol employing spatio-temporally correlated photons from
either entangled or chaotic sources to address the main limitations of
conventional light-field imaging, namely, the poor spatial resolution and the
reduced change of perspective for 3D imaging. However, the application
potential of high-resolution imaging modalities relying on photon correlations
is limited, in practice, by the need to collect a large number of frames. This
creates a gap, unacceptable for many relevant tasks, between the time
performance of correlated-light imaging and that of traditional imaging
methods. In this article, we address this issue by exploiting the photon number
correlations intrinsic in chaotic light, combined with a cutting-edge ultrafast
sensor made of a large array of single-photon avalanche diodes (SPADs). This
combination of source and sensor is embedded within a novel single-lens CPI
scheme enabling to acquire 10 volumetric images per second. Our results place
correlated-photon imaging at a competitive edge and prove its potential in
practical applications.
