SCANNING DEVICE WITH POINT-TO POINT FOCUSING

Method and opto-electronic measuring device (1) for measuring of an object's surface with a measuring rate of at least one thousand object points (P, Px, P1, P2, P3) per second. Using a high-speed autofocus optical module comprising at least one variable focal length lens (2, 2a) or reconfigurable optical phase plate having a response time of under 1ms, situated in an emitting beam path (9), there is a real-time focus adaption of the measurement beam within a single object point measurement period.
