Abstract
The theory of canonical transforms is applied to establish the mathematical foundations of the operator algebra method, leading to useful relations between geometrical ray optics and the operator representation of wave optics. The transfer operator of a general first-order system is expressed in terms of the elements of the ray-transfer ABCD matrix. The theory is exemplified through the discussion of basic operator subgroups and special types of systems: Fourier, Fresnel, imaging, and afocal.
