anomaloscopeとは 意味・読み方・使い方

語源

A 1910 photograph of Willibald A. Nagel (1870–1911), a German physiologist who announced his invention of the anomaloscope in 1898 (though it was then given a different name)

From German Anomaloskop, from Ancient Greek ἀνώμαλος (anṓmalos, “irregular, uneven”) (from Ancient Greek ᾰ̓- (a-, “a-, prefix meaning ‘not’”) + ὁμᾰλός (homalós, “even, level”)) + σκοπέω (skopéō, “to look, to look at; to examine, to inspect”) (from Proto-Indo-European *sḱop, ultimately from *speḱ- (“to see; to look, to observe”)).

名詞

anomaloscope (複数形 anomaloscopes)

1. (ophthalmology) An instrument used to test for color blindness by measuring quantitative and qualitative anomalies in color perception.

     The anomaloscope contains a red-green scale from which may be read a number that is proportional to the amount of red in the mixture field, and a Y scale from which is read a number proportional to the luminance of the test color. In testing an observer, the examiner notes the scale values, which then are available for further transformation as noted for the Nagel anomaloscope.

     For the differentiation between color vision defects of retinal origin and color defects as a result of optic nerve disease the determination of the neutral zone and anomaloscope examination are important.

     Anomaloscopes are instruments that assess the ability to make metametric matches. The results are used for definitive diagnosis and quantitative assessment of color vision status. Anomoloscopes are much more difficult to administer than pseudoisochromatic plates and arrangement tests. The first anomaloscope was designed by Nagel and is based on the color match known as the Rayleigh equation, that is, R + G = Y.
