  2. Digital room correction - Wikipedia

    en.wikipedia.org/wiki/Digital_room_correction

    Digital room correction (or DRC) is a process in the field of acoustics where digital filters designed to ameliorate unfavorable effects of a room's acoustics are applied to the input of a sound reproduction system. Modern room correction systems produce substantial improvements in the time domain and frequency domain response of the sound ...

  3. Wollaston prism - Wikipedia

    en.wikipedia.org/wiki/Wollaston_prism

    A Wollaston prism is an optical device, invented by William Hyde Wollaston, that manipulates polarized light. It separates light into two separate linearly polarized outgoing beams with orthogonal polarization. [1] The two beams will be polarized according to the optical axis of the two right angle prisms. The Wollaston prism consists of two ...

  4. Abbe–Koenig prism - Wikipedia

    en.wikipedia.org/wiki/Abbe–Koenig_prism

    An Abbe–Koenig prism is a type of reflecting prism, used to invert an image (rotate it by 180°). They are commonly used in binoculars and some telescopes for this purpose. The prism is named after Ernst Abbe and Albert Koenig . The prism is made from two glass prisms, which are optically cemented together to form a symmetric, shallow Vee ...

  5. Optical coating - Wikipedia

    en.wikipedia.org/wiki/Optical_coating

    Optical coating. An optical coating is one or more thin layers of material deposited on an optical component such as a lens, prism or mirror, which alters the way in which the optic reflects and transmits light. These coatings have become a key technology in the field of optics. One type of optical coating is an anti-reflective coating, which ...

    Principle of the periscope. The periscope on the left uses mirrors whereas the right uses prisms. a Mirrors b Prisms c Observer's eye Principle of the lens periscope. The two periscopes differ in the way they erect the image. The left one uses an erecting prism whereas the right uses an erecting lens and a second image plane. a Objective lens b ...

  7. Dichroic prism - Wikipedia

    en.wikipedia.org/wiki/Dichroic_prism

    One common application of dichroic prisms is in some camcorders and high-quality digital cameras. A trichroic prism assembly is a combination of two dichroic prisms which are used to split an image into red, green, and blue components, which can be separately detected on three CCD arrays. A possible layout for the device is shown in the diagram.

  8. Levelling - Wikipedia

    en.wikipedia.org/wiki/Levelling

    Levelling or leveling ( American English; see spelling differences) is a branch of surveying, the object of which is to establish or verify or measure the height of specified points relative to a datum. It is widely used in geodesy and cartography to measure vertical position with respect to a vertical datum, and in construction to measure ...

  9. Polarization rotator - Wikipedia

    en.wikipedia.org/wiki/Polarization_rotator

    A polarization rotator is an optical device that rotates the polarization axis of a linearly polarized light beam by an angle of choice. Such devices can be based on the Faraday effect, on birefringence, or on total internal reflection. [1] Rotators of linearly polarized light have found widespread applications in modern optics since laser ...
