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.

Video sensor with range measurement capability

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&#xb0;. A reflected beam from the target passes through the beam splitter and is preferably directed 90&#xb0; 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.
