摘要

A process for the autofocus of an imaging optical sensor (4) of an air image camera or a world space camera (1), wherein the camera (1) at least one lens (2), at least one sensor (4) as well as at least one actuator (5) for the relative displacement of the objective lens (2) and the sensor (4), wherein the camera (1) at least one laser (8, 9) associated therewith, whose emission direction parallel to the optical axis (6) of the camera (1) is aligned, characterized in that an evaluation - and control unit (7) the laser (8, 9) controls a pulsed nature and the received reflected impulse response (11) analyzes, wherein said evaluation - and control unit (7) from the impulse response (11) a virtual object plane (e_V) or virtual object distance (d_V) determined, in their or its a function of the actuator (5) lens (2) and the sensor (4) is displaced relative to one another in parallel with the two laser (8, 9) are used in different spectral regions.
