Quantum Efficiency - Short Article

Quantum efficiency (QE) is the measure of the effectiveness of an imaging device to convert incident photons into electrons. For example, if a sensor had a QE of 100% and was exposed to 100 photons, it would produce 100 electrons of signal. In practice, sensors are never 100% efficient, and different sensor technologies have different QE values.

What is the difference between a thermal IR sensor and a ...

2021-03-09· Infrared radiation (IR) can be detected by thermal IR and quantum IR sensors. A thermal IR sensor uses infrared energy as heat for detection and its sensitivity is independent of wavelengths. Therefore, it can detect objects in the near IR, mid IR, and far IR bands. The non-contact detectors do not require cooling after exposure but have slow response times and low resolution. Melexis ...

Quantum sensor - Wikipedia

A good example of an early quantum sensor is an avalanche photodiode (ADP). ADPs have been used to detect entangled photons. With additional cooling and sensor improvements can be used where photomultiplier tubes (PMT) in fields such as medical imaging. APDs, in the form of 2-D and even 3-D stacked arrays, can be used as a direct replacement for conventional sensors based on silicon diodes ...

A quantum refers to the minimum quantity of radiation, one photon, involved in physical interactions (, absorption by photosynthetic pigments). In other words, one photon is a single quantum of radiation. Sensors that function like traditional quantum sensors, but measure a wider range of wavelengths can be thought of as an ‘extended range’ quantum sensor.
