K correction. K correction converts measurements of astronomical objects into their respective rest frames. The correction acts on that object's observed magnitude (or equivalently, its flux ). Because astronomical observations often measure through a single filter or bandpass, observers only measure a fraction of the total spectrum, redshifted ...
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.
Instead of the solid block of glass of the prism in pentaprism system, here 3 mirrors are used to perform the same task. This is cheaper and lighter, but generally produces a viewfinder image of lower quality and brightness. This optical device is often (more precisely) referred to as roof pentamirror because of the roof-like ridge.
The Pediatric Risk of Mortality ( PRISM) score was developed from the Physiologic Stability Index (PSI) [1] to reduce the number of physiologic variables required for pediatric intensive-care unit (PICU) mortality risk assessment, from 34 (in the PSI) to 14, [2] and to obtain an objective weighting of the remaining variables. [citation needed ...
Color correction is a technical process that fixes color issues and makes footage appear as naturalistic as possible. The idea is for colors to look clean and real, as human eyes would see them in the real world – basically, correcting problems of the underlying image by balancing out the colors, making the whites appear white, the blacks appear black, and making sure that everything is even.
The Canon FD 55mm f/1.2 AL (Japan) of 1971 was the first rectilinear aspheric SLR lens; for FD mount Canon SLRs, and the Asahi SMC Takumar 15mm f/3.5 (Japan/West Germany) of 1975 was the first rectilinear aspheric wide angle SLR lens; for M42 screw mount Asahi Pentax SLRs (co-designed with Carl Zeiss [Oberkochen]). The use of modern precision ...
Celemony Software GmbH is a German musical software company that specializes in digital audio pitch correction software. It produces Melodyne, a popular audio pitch modification tool similar to Auto-Tune , although the program itself is manual tuning software.
Raman Tool Set is a free software package for processing and analysis of Raman spectroscopy datasets. It has been developed mainly aiming to Raman spectra analysis, but since it works with 2-columns datafiles (Intensity vs Frequency) it can deal with the results of many spectroscopy techniques. Beyond the spectra preprocessing steps, such as ...
