  2. Holosun - Wikipedia

    en.wikipedia.org/wiki/Holosun

    Holosun weapons sights have been adopted by the Estonian Military. [1] Holosun products have seen widespread use in Ukrainian service in the Russo-Ukrainian War. [1] Holosun scopes have found their way into Russian service in the war through unconventional routes. [6] They have primarily been imported into Russia for alleged hunting use. [5]

  3. List of optics equations - Wikipedia

    Visulization of flux through differential area and solid angle. As always ^ is the unit normal to the incident surface A, = ^, and ^ is a unit vector in the direction of incident flux on the area element, θ is the angle between them.

  4. Holographic optical element - Wikipedia

    en.wikipedia.org/wiki/Holographic_optical_element

    Holographic optical element (HOE) is an optical component (mirror, lens, directional diffuser, etc.) that produces holographic images using principles of diffraction.HOE is most commonly used in transparent displays, 3D imaging, and certain scanning technologies.

  5. Red dot sight - Wikipedia

    en.wikipedia.org/wiki/Red_dot_sight

    A standard design uses a red light-emitting diode (LED) at the focus of collimating optics, which generates a dot-style illuminated reticle that stays in alignment with the firearm the sight is attached to, regardless of eye position (nearly parallax free).

  6. Point spread function - Wikipedia

    en.wikipedia.org/wiki/Point_spread_function

    By virtue of the linearity property of optical non-coherent imaging systems, i.e., . Image(Object 1 + Object 2) = Image(Object 1) + Image(Object 2). the image of an object in a microscope or telescope as a non-coherent imaging system can be computed by expressing the object-plane field as a weighted sum of 2D impulse functions, and then expressing the image plane field as a weighted sum of the ...

  7. Physics of optical holography - Wikipedia

    en.wikipedia.org/wiki/Physics_of_Optical_Holography

    Optical holography [1] is a technique which enables an optical wavefront to be recorded and later re-constructed. Holography is best known as a method of generating three-dimensional images but it also has a wide range of other applications.

  8. Etendue - Wikipedia

    en.wikipedia.org/wiki/Etendue

    It corresponds to the beam parameter product (BPP) in Gaussian beam optics. Other names for etendue include acceptance, throughput, light grasp, light-gathering power, optical extent, [1] and the AΩ product. Throughput and AΩ product are especially used in radiometry and radiative transfer where it is related to the view factor (or shape factor).

  9. Microphotonics - Wikipedia

    en.wikipedia.org/wiki/Microphotonics

    Microphotonics is a branch of technology that deals with directing light on a microscopic scale and is used in optical networking.Particularly, it refers to the branch of technology that deals with wafer-level integrated devices and systems that emit, transmit, detect, and process light along with other forms of radiant energy with photon as the quantum unit.
