The instinctive reaction when measuring nuclear radiation is to think of a Geiger counter, as the low-pressure gas tube detectors have entered our popular culture through the Cold War. A G-M tube is ...

When the topic is radiation detection, thoughts turn naturally to the venerable Geiger-Müller tube. It’s been around for ages, Russian surplus tubes are available for next to nothing, and it’s easy to ...

Researchers in Japan have developed a new photodiode that can detect in just milliseconds a certain type of high-energy ultraviolet light, called UVC, which is powerful enough to break the bonds of ...

We report on a high-speed temporal and spatial multiplexed single-photon counter with photon-number-resolving capability up to four photons. The infrared detector combines a fiber loop to split, delay ...

The photodiode and detector control the capacitive discharge ignition system for the engine. The photodiode emits light at a single frequency. When this light is reflected from a coupon attached to ...

The circuit of Figure 1 includes a PIN photodiode that detects individual photons of gamma radiation. The reverse bias on the photodiode sometimes creates a depletion region. When such a photon ...

Photodiode is a type of light detector capable of converting light energy into either current or voltage, depending upon the mode of operation. Photodiodes are similar to typical semiconductor diodes ...

Flow cytometers need a mechanism to turn the light of excited fluorophores into an electronic signal. This is done by detectors, of which avalanche photodiodes is an increasingly popular one. The ...

Programmable photonics devices, which use light to perform complex computations, are emerging as a key area in integrated photonics research. Unlike conventional electronics that transmit signals with ...

As photonics technology becomes increasingly sophisticated, optical measurements grow increasingly complex. To make reliable measurements, one must consider the characteristics and interactions of ...

Recent advances in light management by various types of nanostructure 1 have gained much attention in optoelectronic and photonic applications. A good example is advanced light trapping by ...
