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.
Image (a): Lifetime images of beads infused with different Ir compounds and fluorescent plastic acquired with TimepixCam, a previous model of the TPX3Cam.
Image (b): Intensity as a function of time (phosphorescence decays) for areas A1-A4 indicated in (a), with monoexponential fits to the phosphorescence decays and residuals of the fits.
