  • Method for distance measurement for vehicles by measuring transit time of laser pulses
    Patent number: 6665057
    Abstract: A method of distance measurement for vehicles by transit time measurement of laser pulses employs a distance sensor including a transmitter (11) having a pulse generator (1A) for the generation of a laser pulse (L), and a receiver (12) having a transit time measurement circuit (3A) for the detection of a reflected laser pulse (RL) reflected by a target. A cover wall (2), which is partially transparent to laser radiation, defines an installation space in which these elements are arranged, with a transit time of a reflected portion (RT) of the laser pulse (L), reflected by the cover wall (2) to the receiver (12), being measured as a reference time signal for the distance measurement.
