Abstract: Method of and apparatus for measuring thermal radiation geometric configuration factors - any such factor being that fraction of the total radiant energy emitted from an energyradiating surface which is incident on an energy-receiving surface. The method includes the steps of forming an image of the projected area of an energy-radiating surface at a selected location along an energy-receiving surface, making a photographic reproduction of such image, repeating the image-forming and image-reproduction steps at a plurality of selected locations along such energy-receiving surface, providing a configuration factor grid for subdividing any such image into weighted areas equivalent to known thermal radiation geometric configuration factors, and inspecting each photographic reproduction with such grid to measure the area of the image thereon in terms of its radiation configuration factor, thereby enabling all such factors to be averaged to derive a value for the entire energy-receiving surface. The apparatus includes an image-forming assembly comprising primary and secondary mirrors of hemispherical configuration for collecting and forming an image of the energyradiating surface as the area thereof is projected onto the primary mirror, and further comprising an intermediate optical system for receiving such formed image as redirected thereto by the secondary mirror and for transmitting to and focusing such image at an image plane for photographic reproduction.
