Sentences with phrase «avalanche photodiodes»

Krivitsky notes that rod - cell efficiency is comparable to the quantum efficiencies of state - of - the - art human - made single - photon detectors such as photomultipliers (40 per cent) and avalanche photodiodes (50 per cent); remarkably, rod cells occupy an area of only 5 by 50 micrometers and contain their own power supply.

This detector improved the LIDAR's performance compared to the InGaAs avalanche photodiodes typically used to detect 1.5 - micron light.

However, in 2010, an international team of researchers showed that Eve could hack the system by exploiting a weakness in the so - called avalanche photodiodes (APDs) used to detect the individual photons.
