| virtual focus | The point from which divergent rays seem to proceed, or that at which they would meet if prolonged backward. (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) |
| distance of virtual image | <physics> When a simple lens is used as a magnifier for visual observation the eye becomes part of the optical system. A virtual image can be formulated by construction and its apparent distance will vary with the focus of the eye. This will vary among individuals. In a rather arbitrary but standardised assumption, the normal distance for close observation, or reading has been set at 10 inches (250 mm). The optics for the compound microscope have been designed to furnish parallel light from the eyepiece so that the eyes are relaxed for distant viewing. This makes the virtual image lie at infinity. Tests showed that the average observer accommodates somewhat, placing the virtual image rather variably, often about 20 - 25 feet. (05 Aug 1998) |
| image virtual | <microscopy> A virtual image has no real existence. It is the image seen when looking into a mirror. The field of view of the microscope is a good example of a virtual image. When the eye operates in conjunction with a lens to form an image on the retina, the visual sensation is as if the image existed in space. That its apparent location is very definite is proved when a pin can be made to coincide with the mirror (virtual) image of another pin that is seen by looking at a sheet of glass acting as a mirror. With a lens system a virtual image can be definitely located as by graphically tracing rays back to a focus. In a microscope, if the eye is relaxed as it should be, the virtual image will be at infinity. Measurements show that most observers place the aerial image at 20-25 feet, some as close as seven, because of partial accommodation. (11 Mar 1998) |
| 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 image | An image formed by the convergence of the actual rays of light from an object. Synonym: inverted image. (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) |
| image real | <microscopy> An image as formed by a lens on a screen, plate or any plane surface. See: image, virtual. (05 Aug 1998) |
