A combined infra-red camera/image projector viewing system for heat emission visualisation.

摘要

The combination of an infra-red camera and an image projector makes easier the examination of an an object or surface emitting heat as it allows the actual surface to be illuminated directly by a visible representation of the heat emissions from different areas of the surface e.g, wall of a building projected onto the surface of the real object as opposed to viewing these emissions on a monitor screen. A beam splitter may be used to remove the difference in viewing angle between camera and projector. False colour projection or contour lines may be used to delineate areas of different heat emission. The technique may be applied to millimentric radar viewing security systems, in ultrasonic, medical, and non-destructive testing systems and other visualisation measurement systems that would benefit from a projected visual overlay on the object being examined.
