Abstract: The invention relates to a device with a detector element for receiving a light beam reflecting on an object, wherein means for detecting the light beam are provided in the detector element. The invention also relates to a method for distance measurement using said receiver device. A device for determining the distance between a vehicle and an obstacle or a vehicle driving ahead is already known as per DE 197 13 826 A1, wherein a pulsed laser beam serving as send signal scans line-by-line a two-dimensional area using a self-rotating polygonal mirror, wherein said polygonal mirror has a plurality of mirror surfaces that are bent at different angles. The pulse beam reflecting on the object is focused on a detector element by optical lenses.
