Abstract: A distance meter for the high-accuracy single-point distance measurement to a target point by means of an oriented emitted beam, wherein the receiver has an optoelectronic sensor based on an arrangement of microcells for acquiring the received beam. The receiver and a computer unit are configured in this case for deriving a set of runtimes with respect to different cross-sectional components of the received beam acquired using subregions of the receiver, and therefore, for example, an evaluation is enabled as to whether the received beam has parts of the emitted beam reflected on a single target or a multiple target in its lateral extension.
