Defocus aberration

In der Optik ist Defokus die Abweichung, in der ein Bild einfach unscharf ist. Diese Abweichung ist jedem bekannt, der eine Kamera, Videokamera, Mikroskop, Teleskop oder Fernglas benutzt hat. Optisch bezieht sich Defokussierung auf eine Translation entlang der optischen Achse weg von der Ebene oder der Oberfläche des besten Fokus. Im Allgemeinen reduziert Defokussierung die Schärfe und den Kontrast des Bildes. Was sollten scharfe, kontrastreiche Kanten in einer Szene werden, werden allmähliche Übergänge. Feines Detail in der Szene ist verschwommen oder wird sogar unsichtbar. Fast alle bildgebenden optischen Geräte enthalten eine Form der Fokuseinstellung, um die Defokussierung zu minimieren und die Bildqualität zu maximieren. Der Grad der Bildunschärfe für einen gegebenen Betrag der Fokusverschiebung hängt umgekehrt von der Linsenf-Zahl ab. Niedrige f-Zahlen, wie z. B. f / 1.4 bis f / 2.8, sind sehr empfindlich gegenüber Defokussierung und haben sehr geringe Tiefenschärfe. Hohe f-Zahlen, im Bereich f / 16 bis f / 32, sind sehr tolerant gegenüber Defokussierung und haben daher große Tiefenschärfe. Der Begrenzungsfall in f-Nummer ist die Pinhole-Kamera, die bei eventuell f / 100 bis f / 1000 arbeitet. In diesem Fall sind alle Objekte fast unabhängig von ihrer Entfernung von der Lochblende.

In optics, defocus is the aberration in which an image is simply out of focus. This aberration is familiar to anyone who has used a camera, videocamera, microscope, telescope, or binoculars. Optically, defocus refers to a translation along the optical axis away from the plane or surface of best focus. In general, defocus reduces the sharpness and contrast of the image. What should be sharp, high-contrast edges in a scene become gradual transitions. Fine detail in the scene is blurred or even becomes invisible. Nearly all image-forming optical devices incorporate some form of focus adjustment to minimize defocus and maximize image quality. The degree of image blurring for a given amount of focus shift depends inversely on the lens f-number. Low f-numbers, such as f/1.4 to f/2.8, are very sensitive to defocus and have very shallow depths of focus. High f-numbers, in the f/16 to f/32 range, are highly tolerant of defocus, and consequently have large depths of focus. The limiting case in f-number is the pinhole camera, operating at perhaps f/100 to f/1000, in which case all objects are in focus almost regardless of their distance from the pinhole aperture.
