  • Patent number: 5074628
    Abstract: A laser scanning device and a method for operation thereof includes a laser source, and a laser beam deflector assembly. The laser beam deflector assembly includes a motor driven hollow shaft. The rotating hollow shaft includes an optical element at an end portion thereof. The laser source emits a collimated laser beam which passes through the rotating hollow shaft, and is deflected by the rotating optical element mounted within the hollow shaft. The rotating optical element continuously deflects the laser beam and generates a conical-shaped laser beam, which when intercepted produces an inscribed circle. The inscribed circle is collapsed by a scan lens so as to provide uni-directional or multi-directional scan along a desired scan track.

  • Patent number: 4963096
    Abstract: A device and method for improving and refining a shooter's skills has a laser or light beam, when the device is turned on, emitted from a laser diode or a light emitting diode to a collimating lens and through a hollow shaft, and to a prism being rotated by a shaft and motor. The beam is deflected in different directions so that a rapid rotation of the prism permits the beam to form a substantially circular reflecting image. The diameter of the image can be adjusted by adjusting an adjustable lens. When a shooter aims at a clay target, the shooter moves the gun barrel at a sweeping line of sight along a target flight path until the moving target intersects a point on the circumference of the substantially circular image for indicating to the shooter that a proper lead has been achieved for successfully shooting the moving target. Moreover, a receiver can be mounted on the housing for allowing an instructor to evaluate how well the shooter is performing.
