b. A rapid, rhythmic variation in the degree or quality of illumination which is perceptible to the eye; also, the visual sensation caused by this.
1892E. S. Ferry in Amer. Jrnl. Sci. CXLIV. 195 A vibration of the lamp or of the diffraction-grating produces a flicker in the field of view that cannot be distinguished from the appearance produced by a too slow rotation of the sectored disc. 1912Phil. Mag. 6th Ser. XXIV. 370 The fovea is more sensitive to red flicker, the periphery to blue. 1929C. Murchison Found. Exper. Psychol. iv. 200 Chromatic flicker can be evoked by alternating, upon the same retinal area, two stimuli which differ in wave-length composition but which are photometrically equal. 1944W. D. Wright Measurem. Colour iv. 107 The sensation of flicker due to alternations in colour vanishes at a lower frequency of alternation than the flicker due to difference in brightness. 1962H. C. Weston Sight, Light & Work (ed. 2) v. 161 There is ordinarily no visible flicker from flourescent lamps, although sometimes it is apparent at their extremities as seen by peripheral vision.
c. spec. in Cinemat. and Television, a succession of sudden, abrupt changes in a picture, such as occurs when the number of frames per second is too small to produce persistence of vision.
1899H. V. Hopwood Living Pictures vi. 208 A continual rattle impinging on the ear tends to intensify irritation caused to the eye by flicker on the screen. 1923F. A. Talbot Moving Pictures 7 The regularity of this recurring damping wave, described as ‘flicker’, set up severe eye-strain. 1933Discovery May 157/1 The ultra⁓short waves enable images with much greater detail and almost complete absence of flicker to be transmitted. 1953H. A. Chinn Telev. Broadc. i. 6 The minimum acceptable frame frequency is that required for the elimination of flicker. 1968Times 18 Apr. 2/8 (headline) TV flicker led to death.
d. A rapid variation in the quality of a sound analogous to visual flicker (see 2 b above).
1922Physical Rev. XX. 332 It has been found possible..to make use of the perception of flicker in an alternation phonometer. Let two frequencies alternate in the ear at a suitable rate, [etc.]. 1934C. Murchison Handbk. Gen. Exper. Psychol. xvi. 897 The former used a flicker method, the tones to be compared being presented to the ears alternately at the rate of about 25 alternations a second. 1953C. E. Osgood Method & Theory Exper. Psychol. iv. 146 Simultaneous auditory flicker..was found to increase the pronouncedness of visual flicker if it was already present.

4. attrib., as flicker frequency, flicker method; flicker effect Electronics, a relatively low-frequency random fluctuation in the current emitted by a cathode in a thermionic valve, caused by changes in the state of the emitting surface; also, a similar effect in transistors and other solid-state devices; flicker fusion, the apparent steadiness of a regularly varying source of light when the frequency of the variation is sufficiently great; so flicker-fusion frequency, the lowest rate of variation at which flicker is not perceptible; also called critical flicker (or fusion) frequency; flicker noise Electronics, noise due to the flicker effect; flicker photometer, an instrument for measuring the relative intensities of light from two different sources, esp. sources of different colours, by measuring the flicker or observing the absence of flicker when the field of view is illuminated alternately by the two sources of light; so flicker photometry.
1926W. Schottky in Physical Rev. XXVIII. 77 If we had to do with emission of light instead of electrons, we would speak of a chaotic variation of light intensity taking place over the surface of the cathode, a phenomenon which we should describe by the word ‘flicker’. If..Johnson's explanation of the phenomenon is the correct one, then we may use the analogy and call the new effect the ‘*flicker effect’.
1907Nat. Electr. Light Assoc. 30th Convention I. 337 The most sensitive *flicker frequency for small ranges of flicker was in the neighborhood of 2.5 cycles per second. 1922Jrnl. Optical Soc. Amer. VI. 7 The substantial independence of critical flicker frequency upon chroma is..the basis of the critical frequency method of heterochromatic photometry.
1936Jrnl. Gen. Physiol. XIX. 514 *Flicker fusion depends upon the suppression of intensity discrimination. 1944Federation Proc. III. 6 (heading) Changes in flicker fusion frequency (F.F.F.) under experimental stress. 1962H. C. Weston Sight, Light & Work (ed. 2) v. 161 The fluctuation in light output of electric lamps caused by a 50-cycle alternating current..is faster than the usual ‘flicker fusion frequency’ for the bright-adapted eye.
1897Jrnl. Physiol. XXII. 143 The most marked discrepancy between the band and *flicker methods was in the case of red. 1934Flicker method [see 2 d above].
1947Proc. Physical Soc. LIX. 366 At low frequencies (3 to 104 c.p.s.) *flicker noise may be tens or even hundreds of times greater than Johnson or shot noise. 1960D. A. Bell Electr. Noise xii. 274 When working with semiconductors there is always a risk of flicker noise being introduced at the electrode contacts.
1896F. P. Whitman in Physical Rev. III. 241 (heading) On the photometry of differently colored lights and the ‘*flicker’ photometer. 1955J. W. Wentworth Color Telev. Engin. iii. 59 The best instrument for measuring the luminances of ‘colored’ surfaces is the flicker photometer.
1897Jrnl. Physiol. XXI. 47 According to the rules of *flicker-photometry..flicker should disappear from the whole surface of the disc at the same minimal speed.
