An optical system analysis and design methods based on energy conservation law

The present invention provides an optical system analysis and design methods based on energy conservation law, belonging to the field of optical design, optical design software solves the problem can not be added to make the optical film quality of the optical imaging system for handling optical film pre reasonable estimates, resulting in an optical system according to design and processing the resulting optical film is not compatible with the problem. The modulation method from the perspective of energy, strict electromagnetic field theory as a starting point, the establishment of a working interface equivalent, in conjunction with the bare optical system constructed equivalent parameters of the optical system after the addition of an optical film, and the system was evaluated and analyzed. The present invention overcomes the deficiencies of conventional optical design software processing an optical film, the optical film of complex physical processes equivalent to the optical geometrical optics process than conventional optical software saves time and cost.
