| real | Royal; regal; kingly. "The blood real of Thebes." 1. Actually being or existing; not fictitious or imaginary; as, a description of real life. "Whereat I waked, and found Before mine eyes all real, as the dream Had lively shadowed." (Milton) 2. True; genuine; not artificial; counterfeit, or factitious; often opposed to ostensible; as, the real reason; real Madeira wine; real ginger. "Whose perfection far excelled Hers in all real dignity." (Milton) 5. Relating to things, not to persons. "Many are perfect in men's humors that are not greatly capable of the real part of business." (Bacon) 4. <mathematics> Having an assignable arithmetical or numerical value or meaning; not imaginary. 5. Pertaining to things fixed, permanent, or immovable, as to lands and tenements; as, real property, in distinction from personal or movable property. Chattels real, a burden imposed upon one estate in favor of another estate of another proprietor. Synonym: Actual, true, genuine, authentic. Real, Actual. Real represents a thing to be a substantive existence; as, a real, not imaginary, occurrence. Actual refers to it as acted or performed; and, hence, when we wish to prove a thing real, we often say, "It actually exists," "It has actually been done." Thus its really is shown by its actually. Actual, from this reference to being acted, has recently received a new signification, namely, present; as, the actual posture of affairs; since what is now in action, or going on, has, of course, a present existence. An actual fact; a real sentiment. "For he that but conceives a crime in thought, Contracts the danger of an actual fault." (Dryden) "Our simple ideas are all real; all agree to the reality of things." (Locke) Origin: LL. Realis, fr. L. Res, rei, a thing: cf. F. Reel. Cf. Rebus. Source: Websters Dictionary (01 Mar 1998) |
| real focus | The point of meeting of convergent rays. (05 Mar 2000) |
| real-time ultrasonography | Rapid serial ultrasound images produced using a phased array or scanning transducer; produces a video display of organ motion, such as heart valve or foetal motion. (05 Mar 2000) |
| Abbe theory of image formation | <optics, physics> Abbe's theory is based on the fact that a non-self-luminous particle, which is illuminated by an extraneous source, gives rise to diffracted light rays, in addition to the dioptric pencil. He stated that to form a good microscopical image as many of the diffracted rays as possible should be intercepted by the objective. With closely ruled lines, his theory is easily demonstrated by observing the back lens of the objective, for here the diffracted rays can be observed directly if the aperture diaphragm is closed. It can be shown that, when the illumination is arranged to exclude the diffracted images, resolution is lost. (11 Mar 1998) |
| accidental image | Continuation of visual impression after cessation of stimuli causing the original image. (12 Dec 1998) |
| body image | A term for the concept which each individual has of his own body as an object in and bound by space, independently and apart from all other objects. (12 Dec 1998) |
| radiographic image enhancement | Improvement in the quality of an X-ray image by use of an intensifying screen, tube, or filter and by optimum exposure techniques. Digital processing methods are often employed. (12 Dec 1998) |
| radiographic image interpretation, computer-assisted | Computer systems or networks designed to provide radiographic interpretive information. (12 Dec 1998) |
| catatropic image | <ophthalmology, physiology> The two images formed by the anterior and posterior surfaces of the cornea and the two images formed by the anterior and posterior surfaces of the lens. Synonym: catatropic image, Purkinje images, Sanson's images. (05 Mar 2000) |
| virtual image | <microscopy> Such as seen in a mirror or through a magnifier. A virtual image has no real existence in space as does a real image from a lens. It does have a definite location, however, caused by the angles of divergence of the rays received by the eye. This can be shown by the common school experiment of placing a pin coincident with its mirror image behind a sheet of glass acting as a partial mirror. Its location can also be placed in design by extrapolating backwards to a focus. If a magnifier is used as it should be, with the object at its focus, the virtual image is at infinity. The same is true for a microscope focused for the relaxed eye. See: distance of virtual image. (05 Aug 1998) |
| visual image | A collection of foci corresponding to all the luminous points of an object. (05 Mar 2000) |
| retinal image | A real image formed on the retina. (05 Mar 2000) |
| mental image | A picture of an object not present, produced in the mind by memory or imagination. (05 Mar 2000) |
| phase image | A magnetic resonance image showing only phase shift information, to detect motion. (05 Mar 2000) |
| real image |
A real image is the image formed by light rays from an object passing through a convergent (convex) lens. The real image lies on the side of the lens away from the object and is inverted. See also virtual image.

| real image |
The immaterial image that appears in front of the holographic film or plate. Some large holograms (eg rainbow holograms) project real images 2 or 3 m in front of the film. A real image may be orthoscopic or pseudoscopic. Shadowgrams produced using a single step transmission technique (H1) and visible with white light always produce a pseudoscopic real image.
