  2. Rectilinear lens - Wikipedia

    en.wikipedia.org/wiki/Rectilinear_lens

    It allowed distortionless photos to be taken quickly for the first time, and was a standard lens design for 60 years. [1]: 59 As of 2020, the Laowa 9mm f/5.6 lens is the world's widest rectilinear lens for full frame cameras. [2] The vast majority of video and still cameras use lenses that produce nearly rectilinear images.

  3. Linear motion - Wikipedia

    en.wikipedia.org/wiki/Linear_motion

    The linear motion can be of two types: uniform linear motion, with constant velocity (zero acceleration); and non-uniform linear motion, with variable velocity (non-zero acceleration). The motion of a particle (a point-like object) along a line can be described by its position x {\displaystyle x} , which varies with t {\displaystyle t} (time).

  4. Perspective distortion - Wikipedia

    en.wikipedia.org/wiki/Perspective_distortion

    The mood effect of perspective distortion achieved by rectilinear extreme wide-angle lenses is that the resulting image looks grotesque and unsettling, while not looking as unrealistic as curvilinear fisheye lenses which display barrel distortion. The effect is especially noticeable the closer the camera is to the subject, as its amount ...

  5. Motion - Wikipedia

    en.wikipedia.org/wiki/Motion

    [Also known as rectilinear motion] Reciprocal motion; Brownian motion – the random movement of very small particles; Circular motion; Rotatory motion – a motion about a fixed point. (e.g. Ferris wheel). Curvilinear motion – It is defined as the motion along a curved path that may be planar or in three dimensions.

  6. Fisheye lens - Wikipedia

    en.wikipedia.org/wiki/Fisheye_lens

    With appropriate software, the curvilinear images produced by a fisheye lens can be remapped to a conventional rectilinear projection. Although this entails some loss of detail at the edges of the frame, the technique can produce an image with a field of view greater than that of a conventional rectilinear lens.

  7. Rectilinear propagation - Wikipedia

    en.wikipedia.org/wiki/Rectilinear_propagation

    Rectilinear propagation was discovered by Pierre de Fermat. [1] Rectilinear propagation is only an approximation. [citation needed] The rectilinear approximation is only valid for short distances, in reality light is a wave and have a tendency to spread out over time. The distances for which the approximation is valid depends on the wavelength ...

  8. Curvilinear motion - Wikipedia

    en.wikipedia.org/wiki/Curvilinear_motion

    The motion of an object moving in a curved path is called curvilinear motion. [1] Example: A stone thrown into the air at an angle . Curvilinear motion describes the motion of a moving particles that conforms to a known or fixed curve.

  9. History of photographic lens design - Wikipedia

    Harrison & Schnitzer Globe Dallmeyer Rapid-Rectilinear and Steinheil Aplanat. The Achromat Landscape was also afflicted with rectilinear distortion – straight lines were imaged as curved. This distortion was a pressing problem as architecture was an important photography subject early on.
