Photon Detector vs. Thermal Detector

What's the Difference?

Photon detectors and thermal detectors are two types of sensors used in various applications. Photon detectors, as the name suggests, are designed to detect and measure the presence of photons or light particles. They are highly sensitive and can detect even a single photon, making them ideal for applications such as astronomy, quantum physics, and telecommunications. On the other hand, thermal detectors are based on the principle of heat transfer. They detect and measure changes in temperature caused by the absorption of radiation. Thermal detectors are commonly used in thermal imaging cameras, fire detection systems, and industrial applications. While photon detectors offer high sensitivity and precise measurements of light, thermal detectors provide a broader range of detection and are more suitable for applications involving heat transfer.
