Method and apparatus for electronically generating an outline indicating the size of an energy zone imaged onto the IR detector of a radiometer
First Claim
1. 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 an image of at least a part of the object surface;
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 a displayed image of the object surface and with the shape outline indicating the extent of a displayed image included in the energy zone.

Abstract
A radiometer includes a sighting system that generates a digital image of an object surface having an area that is to be imaged onto the IR detector. A shape outline is overlaid on the digital image of an object surface to indicate the extent of the energy zone that is imaged onto the IR detector. A rangefinder measures the distance between the radiometer and the object surface and the measured distance is utilized to determine the size of the overlaid shape.
