Frequently Asked Questions

A detector is a device that converts electromagnetic radiation (such as light) into an electrical signal.

There are several types of detectors, including photodiodes, photomultiplier tubes (PMTs), avalanche photodiodes (APDs), charge-coupled devices (CCDs), and complementary metal-oxide-semiconductor (CMOS) sensors.

A photodiode is a semiconductor device that generates a current proportional to the incident light intensity. A photomultiplier tube, on the other hand, uses a photocathode to generate electrons that are then multiplied by a series of dynodes, resulting in a much higher current output.

The dark current of a detector is the electrical current that flows through the detector even when no light is present. It is caused by thermally generated carriers in the detector material.

The dynamic range of a detector is the ratio of the maximum measurable signal to the minimum detectable signal. A detector with a high dynamic range is able to detect both weak and strong signals.

Quantum efficiency is the ratio of the number of electrons generated by a detector per incident photon. A detector with a high quantum efficiency is able to convert a large percentage of incident photons into electrical signals.

The responsivity of a detector is the ratio of the output signal to the input signal. It is a measure of how efficiently the detector converts incident light into an electrical signal.

The spectral response of a detector is the range of wavelengths of light that the detector is sensitive to. Different types of detectors have different spectral responses, which can be tailored to specific applications.

The noise equivalent power (NEP) of a detector is the minimum detectable power level that can be distinguished from noise. A detector with a low NEP is able to detect very weak signals with high accuracy.

Did You know?

Detectors are devices that convert electromagnetic radiation, such as light, into an electrical signal. They are widely used in a variety of applications, including scientific research, medical imaging, and industrial inspection. There are several types of detectors, each with its own unique properties and advantages. Photodiodes are simple and reliable, while photomultiplier tubes offer high sensitivity and fast response times. Avalanche photodiodes and charge-coupled devices are commonly used in low-light applications, while complementary metal-oxide-semiconductor sensors are used in digital cameras and other consumer devices. One important factor to consider when choosing a detector is its spectral response, which determines the range of wavelengths of light that the detector is sensitive to. Other important factors include the detector's quantum efficiency, which measures its ability to convert incident photons into electrical signals, and its dynamic range, which measures its ability to detect both weak and strong signals. Detectors are subject to various sources of noise, including thermal noise, shot noise, and dark current. To minimize noise and improve performance, detectors are often cooled to low temperatures or operated in a vacuum environment.
