Patent ID: 7164467

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 for displaying a displayed image of at least a part of the object surface not included in the energy zone and of at least a part of the object surface included in the energy zone; a range-finding sub-system for measuring the distance between the non-contact IR thermal measurement device and the object surface and outputting a distance signal indicating a measured distance; and an optical overlay sub-system, coupled to the range-finding sub-system, for overlaying a shape outline, having a dimension determined by a received measured distance, over the displayed image of the object surface and with the shape outline indicating the extent of a displayed image included in the energy zone.
