Fourier Optics 1 Background Ray optics is a convenient tool to determine imaging characteristics such as the location of the image and the image magniﬂcation. A complete description of the imaging system, however, requires the wave properties of light and associated processes like diﬁraction to be included.

Fourier Optics• Fourier Optics is the application of linear shift invariant system theory to optical systems• The plane wave in an optical system is represented by the multivariate complex exponential just like the sine wave in an LTI system is represented by the j t single variable e• Just like an electrical signal can be represented as summation of sine waves, an optical image can be Fourier optics is the study of classical optics using Fourier transforms (FTs), in which the wave is regarded as a superposition of plane waves that are not related to any identifiable sources; instead they are the natural modes of the propagation medium itself. 94 relations.
