Royal Philips Electronics scientists have reportedly developed a digital silicon photomultiplier technology that will allow photon counting in applications where ultra-low light levels need to be measured.

Areas where the new technology could be useful include medical imaging, in particular PET and in-vitro diagnostic tests such as DNA sequencing and protein/DNA microarrays, according to the company.

Philips said its technology combines single-photon detectors (silicon avalanche photodiodes) with low-voltage CMOS logic on the same silicon substrate.
