Beschreibung
Zusammenfassung:	The invention provides a means of enhancing the dynamic range and linearity of photodetectors and imaging photodetector arrays. This is achieved by combining Geiger mode avalanche photodiodes (APDs) capable of high efficiency detection of single photons and conventional semiconductor photodetectors with poor noise floors to simultaneously achieve high efficiency detection of single photons and a wide dynamic range.
