Method and device for accelerated calculation of wavefronts through a complex optical system

A device for simulating an optical system by means of calculating a wavefront, wherein the optical system is a complex optical system whose effect exceeds a single refraction, a single propagation, or a single reflection, comprising:

• a modeling module designed to provide at least one wavefront transfer function for the optical system, wherein the wavefront transfer function is designed to assign an associated emergent wavefront to every wavefront entering into the optical system, under consideration of imaging errors with an order greater than the order of defocus;
• and
• an evaluation module designed to evaluate the at least one wavefront transfer function for at least one wavefront entering into the optical system.
