  2. Prism correction - Wikipedia

    en.wikipedia.org/wiki/Prism_correction

    Prism dioptres. Prism correction is commonly specified in prism dioptres, a unit of angular measurement that is loosely related to the dioptre. Prism dioptres are represented by the Greek symbol delta (Δ) in superscript. A prism of power 1 Δ would produce 1 unit of displacement for an object held 100 units from the prism. [2]

  3. High-speed photography - Wikipedia

    en.wikipedia.org/wiki/High-speed_photography

    Muybridge's photographic sequence of a race horse galloping, first published in 1878.. High-speed photography is the science of taking pictures of very fast phenomena. In 1948, the Society of Motion Picture and Television Engineers (SMPTE) defined high-speed photography as any set of photographs captured by a camera capable of 69 frames per second or greater, and of at least three consecutive ...

  4. Chromatic aberration - Wikipedia

    en.wikipedia.org/wiki/Chromatic_aberration

    Chromatic aberration. In optics, chromatic aberration ( CA ), also called chromatic distortion, color aberration, color fringing, or purple fringing, is a failure of a lens to focus all colors to the same point. [1] [2] It is caused by dispersion: the refractive index of the lens elements varies with the wavelength of light.

  5. Lens - Wikipedia

    en.wikipedia.org/wiki/Lens

    A camera lens forms a real image of a distant object. The above equations also hold for a thick lens if S 1 {\textstyle S_{1}} , S 2 {\textstyle S_{2}} , and f {\textstyle f} are with respect to the principal planes of the lens ( f {\textstyle f} is the effective focal length in this case). [22]

  6. Optical aberration - Wikipedia

    en.wikipedia.org/wiki/Optical_aberration

    Optical aberration. 1: Imaging by a lens with chromatic aberration. 2: A lens with less chromatic aberration. In optics, aberration is a property of optical systems, such as lenses, that causes light to be spread out over some region of space rather than focused to a point. [1]

  7. Aberrations of the eye - Wikipedia

    en.wikipedia.org/wiki/Aberrations_of_the_eye

    Spherical aberration is the cause of night myopia and is commonly increased after myopic LASIK and surface ablation. It results in halos around point images. Spherical aberration exacerbates myopia in low light (night myopia). In brighter conditions, the pupil constricts, blocking the more peripheral rays and minimizing the effect of spherical ...

  8. Distortion (optics) - Wikipedia

    en.wikipedia.org/wiki/Distortion_(optics)

    Lensfun is a free to use database and library for correcting lens distortion. OpenCV is an open-source BSD-licensed library for computer vision (multi-language, multi-OS). It features a module for camera calibration. DxO's PhotoLab software can correct complex distortion, and takes into account the focus distance.

  9. Prism (optics) - Wikipedia

    en.wikipedia.org/wiki/Prism_(optics)

    Prism (optics) An optical prism is a transparent optical element with flat, polished surfaces that are designed to refract light. At least one surface must be angled — elements with two parallel surfaces are not prisms. The most familiar type of optical prism is the triangular prism, which has a triangular base and rectangular sides.
