In that case, the angular resolution of an optical system can be estimated (from the diameter of the aperture and the wavelength of the light) by the Rayleigh criterion defined by Lord Rayleigh: two point sources are regarded as just resolved when the principal diffraction maximum (center) of the Airy disk of one image coincides with the first ...

The ability of a lens to resolve detail is usually determined by the quality of the lens, but is ultimately limited by diffraction.Light coming from a point source in the object diffracts through the lens aperture such that it forms a diffraction pattern in the image, which has a central spot and surrounding bright rings, separated by dark nulls; this pattern is known as an Airy pattern, and ...
Sparrow's resolution limit is nearly equivalent to the theoretical diffraction limit of resolution, the wavelength of light divided by the aperture diameter, and about 20% smaller than the Rayleigh limit. For example, in a 200 mm (eight-inch) telescope, Rayleigh's resolution limit is 0.69 arc seconds, Sparrow's resolution limit is 0.54 arc seconds.
The conventional diffraction-limited resolution is given by the Rayleigh criterion as /, where is the numerical aperture and is the wavelength of the illumination source. It is often common to compare the critical feature width to this value, by defining a parameter, k 1 , {\displaystyle k_{1},} such that feature width equals k 1 λ / N A ...
Then the resolution-independent version is rendered as a raster image at the desired resolution. This technique is used by Adobe Illustrator Live Trace, Inkscape , and several recent papers. [ 6 ] Scalable Vector Graphics are well suited to simple geometric images, while photographs do not fare well with vectorization due to their complexity.
Video editing software or a video editor is software used for performing the post-production video editing of digital video sequences on a non-linear editing system (NLE). It has replaced traditional flatbed celluloid film editing tools and analog video tape editing machines.
As some older systems might not be able to run the new version of Windows Movie Maker, Microsoft also released an updated older version 2.6 for Windows Vista on Microsoft Download Centre. This version is basically the same as Windows Movie Maker 2.1 and included all of the old effects and transitions, but it excludes the ability to capture video.
