Geometrical optics, in which light is characterized as rays or beams, provides an efficient and scalable formalism for the modeling and analysis of optical and laser systems. The main applications of geometrical optics are in stability analysis of optical resonators, laser mode locking and Quasi-optical systems. Traditionally, the analysis of such applications has been carried out by informal techniques like paper-and-pencil proof methods, simulation and computer algebra systems. In this research project, we propose a higher-order logic formalization of geometrical optics which includes optical imaging, optical resonators and Gaussian beams. Our formalization is mainly based on theories of multivariate analysis in the HOL Light theorem prover. In order to demonstrate the effectiveness of our proposed approach, we conduct the formal analysis of some real-world optical systems, e.g., an ophthalmic device for eye, a Fabry-Perot resonator, an optical phase-conjugated ring resonator and a receiver module of the APEX telescope.
