In the field of optoelectronic devices, biased detectors are a widely used category of specialized detection equipment. They are not devices with a single structure, but a general term for optical detection devices operating on the "reverse bias" mode. Their core lies in improving detection performance through external voltage regulation to meet the demand for high-precision optical signal capture...

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...
