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 θin the retinal hazard region which further comprises at least one diffuser wherein the divergence angle after the diffuser is θ; 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.
