Focal-plane shutter — In camera design, a focal plane shutter is a type of photographic shutter that is positioned immediately in front of the focal plane of the camera, that is, right in front of the photographic film or image sensor. AdvantagesOne of the main… … Wikipedia
Focal length — The focal length of an optical system is a measure of how strongly it converges (focuses) or diverges (diffuses) light. A system with a shorter focal length has greater optical power than one with a long focal length. Thin lens approximation For… … Wikipedia
Focal mechanism — The focal mechanism of an earthquake describes the inelastic deformation in the source region that generates the seismic waves. In the case of a fault related event it refers to the orientation of the fault plane that slipped and the slip vector… … Wikipedia
Affine focal set — In mathematics, and especially affine differential geometry, the affine focal set of a smooth submanifold M embedded in a smooth manifold N is the caustic generated by the affine normal lines. It can be realised as the bifurcation set of a… … Wikipedia
History of the single-lens reflex camera — The history of the single lens reflex camera predates the invention of photography in 1826/27 by one and a half centuries with the use of a reflex mirror in a camera obscura first described in 1676. Such SLR devices were popular as drawing aids… … Wikipedia
