What is an APD detector?
Dec 03 , 2025
The full name of an APD detector is Avalanche Photodiode detector. It is a high-sensitivity photoelectric detection device whose core function is to convert weak optical signals into measurable electrical signals. It is widely used in fields such as optical communication, laser ranging, and low-light imaging. Compared with ordinary photodiodes, its biggest advantage lies in its signal am...
