1 de jul. de 2024 · This article provides an overview of electron diffraction and electron diffraction patterns, collective referred to by the generic name electron diffraction. This includes aspects of how in a general way electrons can act as waves, and diffract and interact with matter.
27 de jun. de 2024 · Diffractive optical elements (DOEs) enable precise control over the direction and filtering of light, making them common components in spectrometers, waveguides, and sensors. There is great interest in tunable and sub-micron diffractive optical elements in flexible photonics and for responsive structural colors.
Há 4 dias · For the z direction, we follow the symmetries of a diffraction-limited spot (i.e., lower stiffness axial trapping) and require that κ z = κ x /3.2. We do note, however, that any desired aspect ratio between the stiffnesses along different dimensions can be specified (see section S5).
Há 1 dia · Second, while there are multiple techniques that can focus monochromatic light efficiently to a very narrow diffraction-limited spot within scattering media, it turns out that it is not so simple ...
14 de jun. de 2024 · A pulsed laser created optical nanostructures (holograms) on hydrogel-based soft contact lenses. The nanostructures produced varying diffraction patterns in response to the environmental changes.
11 de jun. de 2024 · The rings of light, with angular diameters of a few degrees, are created by the interplay of refraction, reflection, and diffraction in the water droplets. The glory, once a phenomenon rarely observed, is now frequently seen by airline travelers as coloured rings surrounding their airplane’s shadow on a nearby cloud.
11 de jun. de 2024 · Light - Wave, Interference, Diffraction: The observation of interference effects definitively indicates the presence of overlapping waves. Thomas Young postulated that light is a wave and is subject to the superposition principle; his great experimental achievement was to demonstrate the constructive and destructive interference of ...
