  • Laser scanning system and applications
    Patent number: 6115114
    Abstract: A laser scanner sensor for measuring the spatial properties of objects in a scene within a range less than a predetermined maximum object distance. Applications of the laser scanner system includes measurement of the dimensional weight of parcel(s) being transported by a moving forklift. In the laser scanner sensor, a laser diode supplies a laser beam that is intensity-modulated by a reference waveform from a waveform generator. A variation of the optical scanning sensor system scans a field of measurement which the moving forklift traverses. The forklift has at least three retroreflectors attached to act as calibration targets within the viewing field.

  • Laser scanning system
    Patent number: 5940170
    Abstract: A laser scanner for measuring the spatial properties of objects in a scene within a range less than a predetermined maximum object distance. A laser diode supplies a laser beam that is intensity-modulated by a reference waveform from a waveform generator. An optical scanning system scans the scene with the intensity-modulated laser beam, and receives reflected intensity-modulated light and supplies it to an optical processing system that includes an aperture that transmits a first percentage of light reflected from the maximum object distance and a second, lesser percentage of light reflected from objects closer than the maximum object distance. A photodetector receives the processed light and converts the energy into an amplitude-modulated range signal. A mixer down-converts the frequency into an IF frequency, and a first circuit converts the range signal to the form of a square wave.
