His Optics is a part of the science of Geometrical Optics, and all his other works are comparable to the works of his eminent successor. Furthermore, in the limit r [right arrow] [infinity] these solutions must correspond to the optical field according to geometrical optics, and in this respect it is necessary to distinguish three regions of space as indicated in Fig. Because the former angle is larger than the latter one, geometrical optics suggests that the total power detected depends only on the blackbody temperature and a geometrical factor related to the pinhole aperture, detector optics, and relative separation, because the detector pupil is overfilled. |
