The disclosure relates to a method for detecting the presence of an object near a detection device, comprising: emitting pulses of an incident photon beam, detecting photodiodes which trigger avalanche after the reception by the photodiode of at least one photon of a reflected photon beam produced by a reflection of the incident beam on an object near the detection device, determining a distance between the photodiodes and an object in a detection area, as a function of the time between a transmit time of the incident beam and avalanche triggering times of the photodiodes, and correcting the distance determined as a function of a calibration measurement obtained in the absence of object in the detection area, to compensate for photon reflections on a transparent plate arranged between the photodiodes and the detection area.
