The homologous rays in holographic interferometry may be used for interpretation of localization of the interference pattern and fringe spacing as well. At certain observation conditions and idealizations the two interfering fields are homologous when the intensity of the field one in a small volume about a point P is identical to the intensity of the field two in a similar volume about a point P; close to P. The concept can be generalized in difference holographic interferometry, which provides a means for comparision of the deformations, shapes of two nominally identical diffusely reflecting objects and the refractive index change distributions of two transparent objects. The paper presents how the concept of the homologous rays can be handled in difference holographic interferometry without going deeply into details of the mathematics.
