Abstract
A method and apparatus for the rapid measurement of the distance of an object from a reference point and the speed component of an object traveling vertical to a reference plane is disclosed. A laser beam from a transmitter is periodically sent by a beam deflector through the space in which the object is situated. The laser beam is diffusely reflected from the object and is registered as a measurement pulse on a detector placed near the transmitter. The distance of the object is determined from the time difference between one starting point of a deflected beam segment selected for the measurement and the detector signal. A reference pulse is created in an additional reference detector at a reference time by positioning a swing mirror so that a portion of the laser beam is reflected on a transparent body situated on the reference plane, the reflection then impinging upon the reference detector. The time difference is measured from the reference time to the middle of the measurement pulse.
