The Effect of Light Entrainment Observed in an Optical Disk Interferometer. V.O. Gladyshev, T.M. Gladysheva and V.E. Zubarev. // Technical Physics Letters, Vol. 28, No. 2, 2002, pp. 123Ц125. Translated from PisТma v Zhurnal Tekhnicheskoi Fiziki, Vol. 28, No. 3, 2002, pp. 88Ц94.

We observed a spatial effect of the light entrainment at a wavelength of λ = 0,632991 μm by an optical disk with a radius of R0 = 0,06 m rotating at a frequency of ω = 0,25 Hz.
 A relative shift of the interference pattern, monitored by the time of the interference band motion across the aperture of a photodetector for the disk rotating in the opposite directions, amounted to Δ = 0,0094 ± 0,0025 of the interference bandwidth.
