What Does SPAD Stand For?
SPAD stands for Single Photon Avalanche Diode
A Single Photon Avalanche Diode (SPAD) is a highly sensitive semiconductor device designed to detect individual photons. Utilizing the principle of avalanche multiplication, SPADs achieve high gain and fast response times, making them ideal for applications in photon counting, medical imaging, quantum communication, and various scientific research fields. Their ability to operate under low-light conditions and provide precise timing information enhances their utility in cutting-edge technologies.
