Detector technologies encompass a wide range of devices designed to sense and measure physical phenomena. These technologies are fundamental to scientific research, industrial processes, and everyday applications. Broadly, detectors can be classified by the type of radiation or phenomenon they are designed to detect.

Optical detectors, for instance, convert light into an electrical signal. This includes photodiodes, photomultiplier tubes, and charge-coupled devices (CCDs) used in cameras and telescopes. Thermal detectors measure changes in temperature, often by relying on the thermoelectric effect or resistance changes in materials. Examples include thermistors and thermocouples.

Particle detectors are crucial in high-energy physics and nuclear science. They identify and measure the properties of subatomic particles, such as their energy, momentum, and charge. Techniques like scintillation, Cherenkov radiation, and semiconductor junction detection are employed.

In the realm of radio and microwave frequencies, antennas and specialized receivers are used to detect electromagnetic waves. These are vital for communication systems, radar, and radio astronomy. Furthermore, various sensors exist for detecting chemical substances, pressure, magnetic fields, and motion, each employing unique physical principles to translate external stimuli into measurable outputs. The continuous development of detector technologies drives innovation across numerous scientific and technological fields.
