reportActive / Technical Report | Accession Number: AD0636154 | Need Help?

Abstract:

A method is presented for the determination of the absolute acceleration of gravity. A reflector, terminating one arm of an interferometer is allowed to drop in a vacuum chamber. The fringes generated as the reflector falls, together with precise timing equipment, may permit measurements to be made with an accuracy of one part in 10 to the 7th power. Design criteria for the instrument are presented. Author
