Abstract The invention relates to a device (1) for measuring a surrounding area (2) using a transit time measurement of laser beams (4i) reflected thereon, comprising a beam deflecting device (13) with at least one mirror surface (18 - 25), which can be rotated or vibrated about a rotational axis (26) that is not normal to the mirror surface, and comprising a first laser transmitter (111) with a corresponding first laser receiver (141) and a second laser transmitter (112) with a corresponding second laser receiver (142), each of the transmitter and receiver devices (301, 311, 302; 312) thereof being arranged parallel to one another in pairs and lying at different angles (?1, ?2) to the rotational axis (26), wherein the first laser receiver (141) is arranged at a distance (PX) to the first laser transmitter (111), and the second laser receiver (142) is arranged at a distance (PX) to the second laser transmitter (112), in each case in the direction of the rotational axis (26). L'invention concerne un dispositif (1) de mesure d'une zone environnante (2) à l'aide d'une mesure de temps de propagation de faisceaux laser (4i) réfléchis sur ce dernier, comprenant un dispositif de déviation de faisceaux (13) comportant au moins une surface de miroir (18 à 25), qui peut tourner ou vibrer autour d'un axe de rotation (26) non perpendiculaire à la surface de miroir, et comprenant un premier émetteur laser (111) comportant un premier récepteur laser correspondant (141) et un second émetteur laser (112) comportant un second récepteur laser correspondant (142), chacun de leurs dispositifs émetteurs et récepteurs (301, 311, 302 ; 312) étant disposés parallèlement par paires et suivant des angles différents (?1, ?2) par rapport à l'axe de rotation (26). Le premier récepteur laser (141) est disposé à une distance (PX) du premier émetteur laser (111) et le second récepteur laser (142) à la distance (PX) du second émetteur laser (112), dans chaque cas selon la direction de l'axe de rotation (26).
