Optics in the Kodak Research Laboratories has largely paralleled the development of this field of science throughout this country and the rest of the world in the last half century. In the earlier part of this period, the emphasis was on geometrical optics and especially problems related to lens design and analysis. Later, frequency-response methods became important and, with them, more emphasis on wave theory and diffraction theory. Some work was done at Kodak on radiative transfer and multiplescatter problems because of their close relation to the optics of photographic emulsions.
