Abstract
Disclosed is a random light collector device including a reflecting cavity configured to enclose a random light source that randomly transmits photons. The reflecting cavity has an inner wall adapted to reflect at least a portion of the photons to an output port and guiding means for directing the photons to a photodetector. The guiding means is a hollow tube having an inner wall adapted to reflect the photons, wherein a first end of the hollow tube is connected to or positioned adjacent to the output port of the reflecting cavity and wherein the photodetector is provided within the hollow tube or at a second end such that a sensitive area of the photodetector covers the cross-section of the second end.
