    "abstract": "Optical Doppler shift demonstration experiments are not a simple task since\nthe light source cannot usually be moved in a sufficiently smooth and uniform\nmanner to keep the level of noise well below of that of the signal. For that\nreason most demonstration experiments are usually performed with sound or with\nmicrowaves. Previous work have been reported using a moving mirror in order to\nproduce a moving light source, but small perturbation of its trajectory, as\nsmall as the optical wavelength, can produce a large noise. Using a rotating\nmirror, in which one beam is reflected from the advancing side and the other\nbeam is reflected from the receding part of a rotating mirror, can overcome\nmany of the noise generating effects. In the present work we report the\nconstruction and operation of a demonstration apparatus for measuring optical\nDoppler shift based on a rotating mirror.",
