aperture field method
1Aperture — For other uses, see Aperture (disambiguation). f stops demonstrated on a lens …
2Depth of field — The area within the depth of field appears sharp, while the areas in front of and beyond the depth of field appear blurry …
3Near-field scanning optical microscope — Near field scanning optical microscopy (NSOM/SNOM) is a microscopic technique for nanostructure investigation that breaks the far field resolution limit by exploiting the properties of evanescent waves. This is done by placing the detector very… …
4Interferometric synthetic aperture radar — Interferometric synthetic aperture radar, also abbreviated InSAR or IfSAR, is a radar technique used in geodesy and remote sensing. This geodetic method uses two or more synthetic aperture radar (SAR) images to generate maps of surface… …
5Near and far field — This article is about the electromagnetic concept. For the mathematical, see Near field (mathematics). Antenna field regions for antennas that are shorter than the wavelength of the radiation they emit, such as the whip antenna of a citizen s… …
6Light field — The light field is a function that describes the amount of light traveling in every direction through every point in space. Michael Faraday was the first to propose (in an 1846 lecture entitled Thoughts on Ray Vibrations ) that light should be… …
7Inverse synthetic aperture radar — (ISAR) is a technique to generate a two dimensional high resolution image of a target.In situations where other radars display only a single unidentifiable bright moving pixel, the ISAR image is often adequate to discriminate between various… …
8Synthetically thinned aperture radar — Synthetic Thinned Aperture Radiometry (STAR) is a method of radar in which the coherent product (correlation) of the signal from pairs of antennas is measured at different antenna pair spacings (baselines) [Synthetic Thinned Aperture Radiometry… …
9Spectral phase interferometry for direct electric-field reconstruction — In ultrafast optics, spectral phase interferometry for direct electric field reconstruction (SPIDER) is an ultrashort pulse measurement technique.The basicsSPIDER is an interferometric ultrashort pulse measurement technique in the frequency… …
10Diagonal Method — The Diagonal Method (DM) is a rule of thumb in photography, painting and drawing. Dutch photographer and lecturer Edwin Westhoff discovered the method when, after having long taught the rule of thirds in photography courses, he conducted visual… …
