| barrel distortion | <microscopy> A distortion, or aberration. (05 Aug 1998) |
|---|---|
| geometrical distortion | <microscopy> A lens aberration in which the image is distorted relative to the object. See: aberration, barrel distortion, distortion, pincushion distortion. (05 Aug 1998) |
| perceptual distortion | Lack of correspondence between the way a stimulus is commonly perceived and the way an individual perceives it under given conditions. (12 Dec 1998) |
| pincushion distortion | <microscopy> A geometrical distortion in a video picture, or a form of optical aberration, that makes the middle of all sides of a square appear to bow inward. The distortion can amount to several percent of the picture height in some intensified camera tubes. See: Aberration, Distortion, Barrel distortion. (05 Aug 1998) |
| specimen distortion | <microscopy> A physical change in the specimen caused by desiccation or heating by the electron beam. (05 Aug 1998) |
| distortion | The state of being twisted out of a natural or normal shape or position. Origin: L. Dis = apart, torsio = a twisting (18 Nov 1997) |
| distortion aberration | The faulty formation of an image arising because the magnification of the peripheral part of an object is different from that of the central part when viewed through a lens. (05 Mar 2000) |
| magnetically insulated transmission line | <radiobiology> Used to transport power efficiently in vacuum lines at very high power densities. Although the cathode is a space-charge limited electron emitter, the electron flow is confined by self-generated or applied magnetic fields. MITL's are used extensively in light-ion-driven inertial confinement fusion. (09 Oct 1997) |
| vertical transmission | <microbiology> Transmission of a pathogen such as HIV from mother to foetus or baby during pregnancy or birth. See: perinatal transmission. (09 Oct 1997) |
| mass action transmission | <epidemiology> Transmission of infection which occurs at a rate directly proportional to the number or density of both susceptibles and infecteds present. Some authors reserve the name mass action for transmission processes of the form b X Y/N , which we associate with STD-type transmission, and describe transmission rates of the form b X Y , as pseudo-mass action ; the two are equivalent if the population size is unchanging. (05 Dec 1998) |
| perinatal transmission | <microbiology, paediatrics> Transmission of a pathogen, such as HIV, from mother to baby during birth. See: Vertical Transmission. (09 Oct 1997) |
| microscopy, electron, scanning transmission | A type of electron microscopy which scans with an extremely narrow beam that is transmitted through the sample. The detection apparatus produces an image whose brightness depends on the atomic number of the sample. It should not be confused with microscopy, electron scanning nor with microscopy, electron, transmission (see microscopy, electron). (12 Dec 1998) |
| Conventional Transmission Electron Microscopy | <technique> A term applied to 'normal' transmission electron microscopy imaging. The electron beam is passed through a thin film sample (typically ~1-200 nm thick). Bright field diffraction contrast images are formed with the direct (undiffracted) beam. Dark field images are formed with a selected diffracted beam. CTEM imaging is used in the general observation of samples and careful selection of the diffracting conditions of the sample will allow the analysis of defect structures within the sample. (05 Aug 1998) |
| scanning transmission electron microscopy | <procedure> Method of electron microscopy in which image formation depends upon analysis of the pattern of energies of electrons that pass through the specimen. Has comparable resolving power to conventional transmission EM. (18 Nov 1997) |
| horizontal transmission | <epidemiology> Transmission occurring generally within a population, but not including vertical transmission. (05 Dec 1998) |
