Figures of merit for single-photon detectors. The most widely quoted figure of merit for photodetectors is the noise equivalent power (NEP)24, and this has proved useful for optical power ...

A new photon detector called PEACOQ can register the arrival times of individual photons with the best timing resolution to date. Developed by Matthew Shaw and colleagues at NASA’s Jet Propulsion ...

Scientists have developed the world's most efficient single photon detector, which is able to count individual particles of light traveling through fiber optic cables with roughly 99 percent ...

This allows improved performance of a single photon detector while using the same avalanche photodiode (J. Phys. D: Appl. Phys. 40 6922). The team has demonstrated that at telecom wavelengths the ...

The special add-ons increased the detector’s absorption efficiency from 20% – the previous best for previous single-photon detectors – to 57% at the wavelength used for broadband signal ...

NASA is awarding a team of researchers from RIT and Dartmouth College a grant to develop a detector capable of sensing and counting single photons that could be crucial to future NASA astrophysics ...

The detector leverages Quanta Image Sensor (QIS) technology, which represents a new way to collect images in a camera. The QIS measures every photon, or individual particle of light, that strikes ...

The R&D 100 Award winners are selected by an independent panel of judges and the editors of R&D Magazine. "The winning of an R&D 100 Award provides a mark of excellence known to industry, government ...

AUREA Technology provides the SPD_OEM_NIR first free-running and gated modes NIR Single Photon Counting OEM module, based on a cooled Geiger-mode InGaAs avalanche photodiode (SPAD). This is the most ...

The camera works by scanning an object using low-intensity pulses of laser light. Each pulse of light is fired until a reflected photon is recorded by a detector in the camera.
