ABSTRACT:
A combined laser position detector, infrared emissivity target and television target includes a light-transparent substrate having a TV target on one side and an infrared target on a second side, with the two targets in registration with one another. Alternatively, the TV and IR target can be on the same side. The substrate is affixed to a housing that includes light-emitting sources behind the targets positioned to direct emitted light through the targets and also includes a recess for receiving a laser position detector with an opening behind the targets to permit light to pass through the targets and to impinge upon the surface of the detector.
