Introduction to Optics is now available in a re-issued edition from Cambridge University Press. For our application, we have used the Fresnel diffraction method which utilized a single Fourier transform to back propagate the wave a distance z = z 2 –z 1 to the reconstruction plane, U z (x, y, z). The preferred method depends on the data under consideration and the preferences of the velocity picker. The rest of the light path is short (2 m). En réalisant des expériences avec des pupilles de formes diverses, Fresnel a pu observer des figures de diffraction en parfait accord avec ses calculs. DIFFRACTION OPTICS Physical basis • Considers the wave nature of light, unlike geometrical optics • Optical system apertures limit the extent of the wavefronts • Even a “perfect” system, from a geometrical optics viewpoint, will not form a point image of a point source • Such a system is called diffraction-limited. Huygen's principle Diffraction effects are traditionally classified into either Fresnel or Fraunhofer types.

A negative value for the parameter shows that the obstruction is below the line of sight and if the value is below -1 there is hardly any loss. This integral may be converted into a convolution form which can be efficiently computed using FFT [ 7, 8 ]. To convert the diffraction efficiency into transmittance in the x direction (in order to be able to compare the scalar-theory results with those from Meep), the diffraction efficiency must be multiplied by the Fresnel transmittance from air to glass and by the cosine of the diffraction angle. Chapter 7 Angular Spectrum Representation The angular spectrum representation is a mathematical technique to describe op-tical ﬁelds in homogeneous media. slit(x0=0, size=100.
