1. A method comprising:
measuring signals of an avalanche photodiode (APD) working in a linear mode when the APD receives no radiation and a compensation for a leakage current of the APD is present;
when the signals exceed a first level, commencing a time delay;
measuring the signals of the APD at an end of the time delay; and
when the signals at the end of the time delay exceed a second level, increasing the compensation for the leakage current.
