Abstract: The invention relates to a method of an optimal arrangement in time of a laser emitter and a detector for a remote sensing application, comprising: —setting a target time unit integration time tp; —translating said time unit integration time into a reduced time ?p and its corresponding power increase factor ??1; —activating both the laser emitter, with a power output corrected by ??1, and the detector for a duration of ?p; —deactivating the emitter and detector after duration ?p; —keep emitter and detector off for the subsequent duration toff=tp??p.The invention further relates to a device implementing said method.

Abstract: The invention relates to a remote sensing device comprising a detector with a predefined field of view (FOV); and an emitter emitting pulses of light with an overall divergence angle ?div in the retinal hazard region which further comprises at least one diffuser wherein the divergence angle after the diffuser is ?0; and at least one lens configured to transform the light from said diffuser to a determined divergence angle matching the FOV of the detector, or to a virtual image of predefined size appropriate in magnitude given the divergence in order to ensure the most restrictive position regarding eye-safety to be at the same position for pulsed and (quasi-)continuous wave operation; and to emit the transformed light. The invention further discloses a smartphone comprising such a remote sensing device characterized by its improved eye-safety properties for myopic people.

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.
