| 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) |
| visual-spatial agnosia | The inability to localise objects or to appreciate distance, motion, and spatial relationships; caused by lesion in the occipital lobe. Compare: simultanagnosia. (05 Mar 2000) |
| spatial | Relating to space or a space. (05 Mar 2000) |
| spatial acuity | The detection of the shape of a test object; e.g., perceiving polygons of the same size but with different numbers of sides. (05 Mar 2000) |
| spatial behaviour | Reactions of an individual or groups of individuals with relation to the immediate surrounding area including the animate or inanimate objects within that area. (12 Dec 1998) |
| spatial filter | <radiobiology> Device consisting of a lens pair and a pinhole aperture stop. Intensity fluctuations over the spatial extent of a laser beam are removed by passing the focused beam through the aperture stop. The pinhole must be placed in a vacuum to prevent air breakdown by the focused beam. These filters are used to counter the effects caused by self-focusing. (09 Oct 1997) |
| spatial formula | A chemical formula in which the arrangement of the atoms or atomic groupings in space are indicated. Synonym: spatial formula. (05 Mar 2000) |
| spatial localization | The reference of a visual sensation to a definite locality in space. (05 Mar 2000) |
| spatial sensing | Mechanism of sensing a gradient in which the signal is compared at different points on the cell surface and cell movement directed accordingly. Translocation of all or part of the cell is not required. See: temporal gradient sensing, pseudospatial gradient sensing. (18 Nov 1997) |
