  • Video sensor with range measurement capability
    Patent number: 7375801
    Abstract: A video sensor device is provided which incorporates a rangefinder function. The device includes a single video camera and a fixed laser spaced a predetermined distance from the camera for, when activated, producing a laser beam. A diffractive optic element divides the beam so that multiple light spots are produced on a target object. A processor calculates the range to the object based on the known spacing and angles determined from the light spots on the video images produced by the camera.

  • Variable distance angular symbology reader
    Patent number: 7017812
    Abstract: A variable distance angular symbology reader utilizes at least one light source to direct light through a beam splitter and onto a target. A target may be angled relative to the impinging light beam up to and maybe even greater than 45°. A reflected beam from the target passes through the beam splitter and is preferably directed 90° relative to the light source through a telecentric lens to a scanner which records an image of the target such as a direct part marking code.
