Fig . 13 shows photos of reference flats being used to check two test flats at different stages of completion, showing the different patterns of interference fringes.

By combining the wave fronts produced by the five separate beams and analyzing the resulting interference fringes, the Cambridge group obtained an impressive image of Betelgeuse's surface detail.

In Cambridge a Myriad computer was used to operate the Ryle Telescope tracking eight dishes across the sky, whilst processing the received interference fringe data in real time.

In the same interferometer they also found interference fringes for C 60 F 48 ., a fluorinated buckyball with a mass of about 1600 u, composed of 108 atoms.

But if all particle charges are integer multiples of, solenoids with a flux of have no interference fringes, because the phase factor for any charged particle is 1 } }.

If the position of the antennas is not known to sufficient accuracy or atmospheric effects are significant, fine adjustments to the delays must be made until interference fringes are detected.
47.
The reference flat is slightly beveled ( only a fraction of a degree of beveling is necessary ) to prevent the rear surface of the flat from producing interference fringes.

The ease with which interference fringes can be observed with a laser beam can sometimes cause problems in that stray reflections may give spurious interference fringes which can result in errors.

It will be possible to exploit the BEC phenomenon in gases in precision measurements of fundamental natural phenomena where sharp resonances in essentially motionless atoms or sharp matter-interference fringes are used.
