Patent ID: 7352445

Claim:
A system for indicating the location of an energy zone on an object surface, with the energy zone being an area on the object surface that is imaged onto an IR detector by the IR optical system included in a non-contact IR thermal measurement device, said system comprising: a video sub-system adapted to display a displayed image of at least a part of the object surface included in the energy zone and a part of the object surface not included in the energy zone; a distance entering interface adapted to enter distance data indicating the distance between the non-contact IR thermal measurement device and the object surface; a shape outline image generating sub-system, coupled to the distance entering interface, adapted to selectively output one of a plurality of shape outline digital images, each having a different dimension, in response to distance data entered with the distance entering interface; and an optical overlay sub-system, coupled to the shape outline image generating sub-system, adapted to overlay a shape outline digital image output by the image generating sub-system over the displayed image of the object surface and with an overlaid shape outline digital image indicating the part of the object surface included in the energy zone and with the shape outline digital image having a dimension determined by entered distance data.
