Abstract
3D imager including at least one pixel, each pixel including a photodetector for detecting photon incidence and a time-to-digital converter system configured for referencing the photon incidence to a reference clock, and further including a reference clock generator provided for generating the reference clock, wherein the reference clock generator is configured for adjusting the frequency of the reference clock on the basis of an estimated time up to a subsequent photon incidence.
