Patent ID: 7339685

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 light source for projecting a light beam spot on the object surface; a video sub-system for displaying a displayed image of at least a part of the object surface and the light beam spot; a shape size determining sub-system, coupled to the video sub-system, that utilizes the video sub-system and location of the light beam spot to determine the size of an energy zone indicating shape to be displayed; and an optical overlay sub-system, coupled to the shape size determining sub-system and video sub-system, for displaying the shape over a displayed image of the object surface and with an overlayed shape indicating the part of the displayed image included in the energy zone.
