An information processing control circuit and a gain control module increase a total amplification factor, in a single timing period, of a gain circuit over time, thereby alleviating an echo signal intensity distortion, and expanding a dynamic ranging range.

A temperature of a linear APD array is monitored in the detecting system to adjust a reverse bias voltage of an APD correspondingly and alleviate unstable gain caused by a temperature change.
