The Laser Gravitational Compass
Ivan S. Ferreira, C. Frajuca, Nadja S. Magalhaes +2
Using the observational properties of Einstein's gravitational field it is shown that a minimum of four non-coplanar mass probes are necessary for the Michelson and Morley interfer…

Omnidirectional Gravitational Wave Detector with a Laser-Interferometric Gravitational Compass
M. D. Maia, Ivan S. Ferreira, Claudio M. G. Sousa +2
Based on the Szekeres-Pirani gravitational compass we suggest the addition of a fourth, non-coplanar mass/mirror to the presently existing laser based gravitational wave observator…
