Abstract: The invention relates to a method of determining 3D information of a target (1000), comprising the steps of emitting, at a start time (TO), a light pulse (200) and detecting a first incident photon by one of said detector elements (32). In further steps, the time of incidence (T1) of the detection of said first incident photon is determined and at said time of incidence (T1), a time window (TW) is opened that has a predetermined duration of time (ΔΤ). In a step, all the photons detected in the window (TW) are associated with the time of incidence (T1) of the detection of said first incident photon. In further steps the cycle is repeated and further first incident photons open again a time window (TW) and so that to each of the individual detector elements (32) that detect further incident photons in the time windows (TW), other time of incidences (TT, T1V) are associated. In further steps, the time difference between the time T1 of the received photons and the time TO of the emitted pulse is determined and new cycles of detecting first incident photons and the opening of a new time window (TW) are repeated and 3D information of the target (1000) is provided. The invention is also achieved by a 3D imager (1) to provide 3D information on a target (1000).

Abstract: The invention relates to a method for measuring a distance to a target in a multi-user environment by means of at least one sensor, comprising: • irradiating the environment by means of a series of radiation pulses, wherein series of radiation pulses are emitted at a determined repetition rate and with a determined random delay; • collecting pulses that are reflected or scattered from the environment to at least a detector connected to at least one chronometer; • assigning a timestamp at every detected pulse on the detector; • subtracting the added delay from every registered timestamp coming from the chronometer, the result corresponding to the time of arrival; • determining the statistical distribution of said time of arrival; • determining the distance to the target from said statistical distribution.

Abstract: The invention relates to a method for measuring a distance to a target in a multi-user environment by means of at least one sensor, comprising: irradiating the environment by means of a series of light pulses, wherein this series of light pulses are emitted by a battery of at least two single light source devices (121, 122) emitting on at least two different wavelengths and/or by a single light source emitting on at least two different wavelengths, and said light pulses being emitted at a determined repetition rate and with a determined randomly selected wavelength; collecting pulses that are reflected or scattered from the environment to at least one detector (211, 212) equipped with a wavelength filter whose pass band corresponds to the selected emitted wavelength; assigning a timestamp at the detection of a pulse by means of at least one chronometer (220) connected to the detector, said timestamps corresponding to the time of arrival (TOA); determining the statistical distribution of said time of arrivals; determining the distance to the target from said statistical distribution.
