1. Writing wholly by one's own hand.
| 1802–12 Bentham Ration. Judic. Evid. (1827) II. 459 Autography or holography. |
2. Physics. [f. after photography, telegraphy, etc., on the basis of ] The process or science of producing and using holograms.
| 1964 Physics Lett. XIII. 308 A well-resolved, magnified ‘image’ of the scattering object has been reproduced..without losing the general simplicity and speed which are characteristic of holography. 1965 New Scientist 19 Aug. 431 The technique, known as holography, relies on the fact that an optical description of an object can be stored as a diffraction pattern instead of as a photograph. 1967 Contemporary Physics VIII. 153 Leith and Upatnieks (1963, 1964) were the first to demonstrate the very striking three-dimensional imaging that could be obtained by holography. 1967 Sunday Times 12 Feb. 8/8 Holography is currently a fashionable topic in the scientific world. 1967 Applied Physics Lett. XI. 294/1 The advantage of using acoustic holography to visualize, in three-dimensional fashion, objects in optically opaque material has been intriguing to many investigators. 1969 H. M. Smith Princ. Holography i. 6 Further work on x-ray holography is still awaiting a small, monochromatic source of x-rays. 1971 Sci. Amer. Dec. 39 In the past 10 years holography has been used to study how objects change shape under strain, to record high-speed events in gas dynamics and to store information with high density. |
