Claim 18:
19. A method of detecting a target object in a monitored zone, comprising:
transmitting light pulses of different intensity;
periodically deflecting the light pulses to scan the monitored zone;
receiving the light pulses reflected or remitted by objects in the monitored zone;
generating a received signal from the light pulses reflected or remitted by objects in the monitored zone; and
evaluating the received signal to determine a distance of a scanned object from a time of flight of a light pulse transmitted and received again,
wherein, for the detection of a target object having a specific reflection capability, light pulses adapted to the reflection capability of the target object and to a distance range are transmitted,
wherein the light pulses are varied in accordance with different distance ranges to distinguish between a target object and another object, and
wherein the intensity of the light pulses is selectively increasable toward large and very small ranges.
