The Rapid Rectilinear also named Aplanat is a famous photographic lens design. The Rapid Rectilinear is a lens that is symmetrical about its aperture stop with four elements in two groups. It was introduced by John Henry Dallmeyer in 1866. The symmetry of the design greatly reduces radial distortion, improving on the Petzval lens. Aplanat ...
The most famous example is the Rapid Rectilinear Lens developed by John Henry Dallmeyer in 1866. 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.
Linear motion, also called rectilinear motion, [1] is one-dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimension. The linear motion can be of two types: uniform linear motion , with constant velocity (zero acceleration ); and non-uniform linear motion , with variable velocity ...
The design is presently used in inexpensive-but-high-quality fast lenses such as the Canon EF 50mm f / 1.8 and Nikon 50 mm f / 1.8D AF Nikkor. It is also used as the basis for faster designs, with elements added, such as a seventh element as in both Canon [ 51 ] and Nikon's 50 mm f / 1.4 offerings [ 52 ] or an aspherical seventh element in ...
A rectilinear polygon is a polygon all of whose sides meet at right angles. Thus the interior angle at each vertex is either 90° or 270°. Rectilinear polygons are a special case of isothetic polygons. In many cases another definition is preferable: a rectilinear polygon is a polygon with sides parallel to the axes of Cartesian coordinates ...
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 ...
Lines in graphic design do not always have to be straight lines and can come in many different shapes. They can appear as a rectilinear, or straight, or in a curvilinear, or curved, form. Straight lines are often used to help communicate the tone of the artwork. Curved lines are often used to help lead the viewer's eye around a work.
Rectilinear prophecy, where a straight line can be drawn from the prophecy to the fulfillment without any branches as in the case of typological interpretations Near-rectilinear halo orbit , a highly-elliptical orbit around a Lagrangian point of a moon, that due to the moons orbital movement, will be nearly rectilinear in some frames of reference.
