Abstract: A method for measuring a distance to a target in a multi-user environment, comprising: irradiating the environment by a series of light pulses, wherein this series of light pulses is emitted by a battery of at least two or a single light source device emitting on at least two different wavelengths, the light pulses being emitted at a determined repetition rate and with a determined randomly selected wavelength; collecting pulses reflected or scattered from the environment to at least one detector equipped with a wavelength filter whose pass band corresponds to the selected emitted wavelength; assigning a timestamp at the detection of a pulse by at least one chronometer 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.

Abstract: 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.
