Spot analysis, spot test analysis, or spot test is a chemical test, a simple and efficient technique where analytic assays are executed in only one, or a few drops, of a chemical solution, preferably in a great piece of filter paper, without using any sophisticated instrumentation. The development and popularization of the test is credited to ...
Selected area (electron) diffraction (abbreviated as SAD or SAED) is a crystallographic experimental technique typically performed using a transmission electron microscope (TEM). It is a specific case of electron diffraction used primarily in material science and solid state physics as one of the most common experimental techniques.
The Arago spot is very sensitive to small-scale deviations from the ideal circular cross-section. This means that a small amount of surface roughness of the circular object can completely cancel out the bright spot. This is shown in the following three diagrams which are simulations of the Arago spot from a 4 mm diameter disc (g = b = 1 m):
As one example, if there is free space between the two planes, the ray transfer matrix is given by: = [], where d is the separation distance (measured along the optical axis) between the two reference planes.
Freeform is a digital whiteboarding application developed by Apple for macOS, iOS, iPadOS, and visionOS devices, first revealed during the 2022 Worldwide Developers Conference, [ 1] and officially launched on December 13, 2022, alongside iOS 16.2, iPadOS 16.2, and macOS 13.1. [ 2] It allows users to create infinitely scaling canvases called ...
An interactive whiteboard ( IWB ), also known as interactive board, interactive display, interactive digital board or smart board, is a large interactive display board in the form factor of a whiteboard. It can either be a standalone touchscreen computer used independently to perform tasks and operations, or a connectable apparatus used as a ...
A Shack–Hartmann (or Hartmann–Shack) wavefront sensor ( SHWFS) is an optical instrument used for characterizing an imaging system. [ 1][ 2] It is a wavefront sensor commonly used in adaptive optics systems. It consists of an array of lenses (called lenslets) of the same focal length. Each is focused onto a photon sensor (typically a CCD ...
