Physical optics software provides laser and diffraction calculations

Nov. 1, 1994
Most optical design and modeling programs are based on geometrical optics, which treats light as rays that travel in straight lines. This model works well for many systems such as cameras and telescopes. For other optical systems such as laser beams, however, diffraction and coherence effects require the use of a physical optics approach, which treats light as a complex amplitude field.
