  Efficient measurement of high-dimensional quantum correlations, especially
spatial ones, is essential for quantum technologies, given their inherent high
dimensionality and easy manipulation with basic optical elements. We propose
and demonstrate an adaptively-gated hybrid intensified camera (HIC) that
combines the information from a high spatial resolution sensor and a high
temporal resolution detector, offering precise control over the number of
photons detected within each frame. The HIC facilitates spatially resolved
single-photon counting measurements. We study the measurement of momentum
correlations of photon pairs generated in type-I spontaneous parametric
down-conversion with the HIC and demonstrate the possibility of time-tagging
the registered photons. With a spatial resolution of nearly 9 megapixels and
nanosecond temporal resolution, this system allows for the realization of
previously infeasible quantum optics experiments.
