Single photon imaging
ASI’s intensified TPX3CAM has relevant application possibilities in single photon imaging. Recently, scientists successfully used the TPX3CAM for full temporal and spatial characterization of polarization-entangled photons produced by Spontaneous Parametric Down Conversions. The novel technique allows for precise determination of Bell inequality parameters with minimal technical overhead, as well as novel characterization methods of the spatial distribution of entangled quantum information. The TPX3CAM will bring new application opportunities in the field of Quantum Information.
In this literature, the intensified TPX3CAM camera is applied as a quantum detector to investigate photonic polarization entanglement. Both imaging and time-stamping of a continuous stream of entangled photons with an excellent spatial and temporal resolution (55 × 55 µm2, 1.5 ns), has been achieved at high SNR. Data-driven readout allows for a high throughput of ≈ 107photons per second, which is several orders of magnitude higher than the conventional cameras.
The intensified version of TPX3CAM can be single photon sensitive. In this configuration the camera is employed in combination with an off-the-shelf image intensifier.
The applications include the wide-field time-correlated single photon counting (TCSPC) imaging, phosphorescent lifetime imaging and any applications requiring time-resolved single photon imaging.
