...). In summary, the diffraction patterns at small and large distances are distinct. This is predominantly the consequence of Fresnel and Fraunhofer approximation. The diffraction patterns for a typical slit function are schematically shown in Fig. 3.10 . FIG. 3.10 Diffraction pattern of a slit at the near...

... f ] } ( 2 π ) 2 U 0 ( k x f , k y f ) . Right after the lens, the curved phase front of the Fraunhofer diffraction can be flattened, and the remaining light field amplitude is the scaled Fourier transform of the input field close to the principal axis, (2.22...

... the photon events on a plane of Fraunhofer diffraction. If each photon travels in a straight line without deflection, the image pattern should be a line. After collecting multiple photon events, one could find that this is not the case. The distribution of hitting points exhibits a statistical pattern...

... = ( 1 − R O C ) c 2 π R O C L . According to Fraunhofer diffraction [Eq. (2.34)], the light field at the focal plane is the scaled Fourier transform of the incoming field before the focusing lens. The formation of a tiny focal spot on the transverse plane can be thought...

...). We have omitted the x axis as there is no change due to the 1D focusing property of the cylindrical lens which is along the y axis. As the propagation distance is large, we can apply Fraunhofer diffraction to determine the diffraction pattern. Accordingly, the complex amplitude...

... h₀ = (i/λd) e^−ikd. Detailed discussion can be found in standard optics textbooks (e.g. Saleh and Teich ). Fraunhofer diffraction Fraunhofer diffraction is a consequence of Fraunhofer approximation, which states that the only waves that contribute...

...Microscopy optical slit Nyquist criterion diffraction Introduction The generation of a planar field is crucial for real-time single-shot sectional imaging of large specimens such as Drosophila larvae and zebrafish embryos. Traditional microscopes have been quite successful for investigating...

...When an aperture (or obstacle) is placed within the cross section of a beam of light and the transmitted light is observed on a screen, the resulting distribution of light is called a diffraction pattern. There are two basic forms of diffraction: Fresnel and Fraunhofer. If both source...

... and observe the range of spectra: emission, continuous, and even Fraunhofer absorption lines. Attaching a diffraction grating to a color video camera that is connected to a monitor or projector permits a large, live display of spectra for classroom use. Advances in the sensitivity of video cameras...
