interferometer

A team at Sandia National Laboratory recently built a cold-atom interferometer—like the one used here—into a rugged package about the size of a shoe box.

The interferometer has much refined the indications of the balance.

The resolving power of the interferometer is found to be somewhat more than double that of a telescope of the same aperture.

By applying the interferometer method to Capella, arc distances of much less than one-twentieth of a second of arc were measured.

Many diverse applications of the interferometer have been developed, as, for example, in thermometry.

In the interferometer the approach of the small ball to the large one produced a displacement of seven whole fringes.
