Hello, below is the screenshot from the book INTRODUCTION TO MODERN DIGITAL HOLOGRAPHY With MATLAB (TING-CHUNG POON, JUNG-PING LIU). This book is free to download. There is a script for Fraunhofer diffraction pattern and equation 1.40 is Fraunhofer diffraction formula in terms of Fourier transfo...
spread of subdomain orientations (where each subdomain <5 μm in size) and showing optical undulatory extinction, it is common for X-ray diffraction intensity to show a continuous mosaic spread or streak along the Debye ring or chi (χ) dimension in a 2D diffraction pattern (Fig. 1B and...
We analysed the acquired images through a custom-written Matlab algorithm that automatically identifies the number of diffraction rings and fits the diffraction pattern to an appropriate functionf. To this end, we first define a square region of interest (ROI) containing the diffraction pattern of ...
PROOF Imaging software. PROOF is custom-written software developed in Matlab for 3D locali- zation of single fluorescent nanoparticles. PROOF automatically recognizes the number of rings in the diffraction pattern of single emitters and, according to this number, it selects an appropriate function...

Diffraction causes a point of light to spread out, forming a circular pattern called anAiry disk. The full equation (Wikipedia) is shownbelow. The radius of the disk(center to first null)is quite simple. rairy=1.22λNwhereλis the wavelength andNis the F-number (f-stop = aperture diamet...
1. Is there a more efficient way to calculate diffraction pattern? Far field calculation is too time consuming!! 2. In far field integration, does it matter if I start to integrate in a smaller domain(inside the near field)? How to choose the size of near field? I have contacted COM...
1. The light beam passes through the grating, producing a characteristic diffraction pattern on a projection surface located outside the cylinder, orthonormal to the main beam of light. The cylinder can be rotated around a non-concentric axis of rotation. As the center of the circumference and...
