electronic detection system
Quick Summary
An electronic detection system, often referred to as a sensor, is a device that detects a physical quantity and responds with a signal. These systems are used in numerous applications, from detecting motion for security to measuring radiation.
Semiconductor detectors, utilizing materials like silicon and germanium, are a key technology. When radiation interacts with these materials, it creates electron-hole pairs. An electric field then collects these charges, generating a current pulse that indicates the presence and energy of the radiation. This technology offers excellent energy resolution and can detect even small amounts of radiation. Detectors also have characteristics like a lower limit of detection, sensitivity, and a linear range, which define their performance.1
