An apparatus for spatially resolved detection of objects has transmission and reception devices, in which transmission and reception regions overlap or intersect in a detection region which is disposed within a monitored zone. The monitored zone covers a detection angle in which the transmitted radiation is reflected by objects. An imaging arrangement is disposed in the propagation path of the transmitted radiation and/or of the reflected radiation and covers the total detection region at the transmission side and/or at the reception side at all times. Spatial resolution is used for influencing the propagation direction of the radiation and/or for the operation of the reception device, in a time varying manner, such that the spacing of the detection region relative to the imaging arrangement and/or the size of the detection region determined by the degree to which the transmission region and the reception region overlap or intersect changes.
