| barrel of oil equivalent | A unit of energy equal to the amount of energy contained in a barrel of crude oil. Approximately 5.78 million Btu or 1,700 kWh. A barrel is a liquid measure equal to 42 gallons. (05 Dec 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) |
