Can SPAD Be Used for Full-Color Image Sensors?
The Electronic Enthusiast Network reports (by Liang Haobin) that the Single-Photon Avalanche Diode (SPAD) is a special semiconductor optoelectronic device capable of single-photon detection. Its core function is to “capture a single photon and convert it into a detectable electrical signal,” essentially serving as a detector with sensitivity to light signals at the “limit level,” … Read more
