Abstract
An optical detection device is disclosed. The device comprises a photoelectric unit, configured to sense incoming photons and to produce electrical signals pertaining to at least a few of the photons within a plurality of temporally resolved time-windows; an analog-to-digital unit, configured to generate digital representation of the electrical signals; and a digital integrating unit, configured to integrate the digital representation over at least part of the temporally resolved time-windows to provide integrated data corresponding to the photons.
