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.
