Gravitational field measuring apparatus for laser gyro

Abstract

To solve the problem that conventional measuring instruments cannot measure gravitational field density.SOLUTION: Double mass discs are arranged such that an optical path of a laser gyro passes through a gap between the discs, and they are acceleratingly rotated in order to generate gravitational field variation in the optical path. The gravitational field variation is detected using an interferometer of the same laser gyro, thereby measuring density of the gravitational field.SELECTED DRAWING: Figure 2
