Why Obviously Non-Zero Shift of Interference Fringes is Interpreted Again as Confirming Negative Outcome of Experiments on Michelson Type Interferometers

Authors: Demjanov V.V.

In the present report I analyze interesting experimental results of laboratory measurements of the speed of aether wind recently (2009) obtained by Dutch researcher V.Haan at Michelson-type interferometer based on fiber optic waveguides transmitting the light with wavelength ~1 μm. Because of a wrong interpretation of his measurements, those proposed at days of Miller (1933) and Shamir&Fox (1968), V.Haan, proceeding from a reliably measured shift of the interference fringe registered by modern phasometric electronics, 40 times underestimated the speed of aether wind (7 km/s), i.e. obtained the same estimations as was earlier reported by Michelson, Miller, Shamir&Foxs and others who also incorrectly interpreted their data. Now I critically discuss the errors of interpretation of the experiment by V.Haan. I show that really he measured the speed of aether wind several hundred km/s. Some proposals are made of modernization of the construction of fiber optics interferometer capable to raise about 5 times the ratio signal/noise in the device. Thus the resolution by the phase shift can be obtained not less than 0.005 of the fringe width.
