Comparison of the optical behaviour of five different multifocal diffractive intraocular lenses in a model eye.
Can E, Senel EC, Holmström STS, Piñero DP. Can E, et al. Sci Rep. 2023 Nov 10;13(1):19646. doi: 10.1038/s41598-023-47102-y. Sci Rep. 2023. PMID: 37950090 Free PMC article.
Measurements were performed on-axis, with 5 of IOL tilt and with 0.5 mm of IOL decentration using 543-nm monochromatic light. Finally, IOL dimensions and diffractive disk profile inspection was performed using the VisIOLA system (Rotlex). ...The induction of 0.5 mm …

High-resolution scanning precession electron diffraction: Alignment and spatial resolution.
Barnard JS, Johnstone DN, Midgley PA. Barnard JS, et al. Ultramicroscopy. 2017 Mar;174:79-88. doi: 10.1016/j.ultramic.2016.12.018. Epub 2016 Dec 25. Ultramicroscopy. 2017. PMID: 28042983
Methods are presented for aligning the pivot point of a precessing electron probe in the scanning transmission electron microscope (STEM) and for assessing the spatial resolution in scanning precession electron diffraction (SPED) experiments. The alignment procedure is per …

Blur Unblurred-A Mini Tutorial.
Strasburger H, Bach M, Heinrich SP. Strasburger H, et al. Iperception. 2018 Apr 18;9(2):2041669518765850. doi: 10.1177/2041669518765850. eCollection 2018 Mar-Apr. Iperception. 2018. PMID: 29770182 Free PMC article.
Perhaps surprisingly-if well known in optometry-the representation of a blur kernel (or point-spread function) for dioptric blur is, to a good approximation and disregarding diffraction, simply a cylinder. Its projection onto the retina is classically referred to as a blur …

Impact of beam size and diffraction effects in the measurement of long-range electric fields in crystalline samples via 4DSTEM.
Heimes D, Chejarla VS, Ahmed S, Hüppe F, Beyer A, Volz K. Heimes D, et al. Ultramicroscopy. 2023 Nov;253:113821. doi: 10.1016/j.ultramic.2023.113821. Epub 2023 Jul 26. Ultramicroscopy. 2023. PMID: 37562100
STEM multislice simulations including both atomic and nm-scale fields prove that this intermediate range begins once diffraction disks start overlapping with the undiffracted beam. The range ends when the diffraction disks' intensities become so low that they do not …

Diffraction patterns in the shadows of disks and obstacles.
English RE Jr, George N. English RE Jr, et al. Appl Opt. 1988 Apr 15;27(8):1581-7. doi: 10.1364/AO.27.001581. Appl Opt. 1988. PMID: 20531617
We compare the Fresnel diffraction pattern of a thin circular disk with that of a square obstacle, specifically evaluating the on-axis field strength. Photographs of the diffraction patterns reveal some curious features for the square obstacle. ...
