Convergent-beam dynamic interferometer for study of relativity theory

摘要

The instrument uses monochromatic sources of coherent light (20,21) such as collimated laser diodes, a biprism (22), a planar array of slits (23) and a photosensitive element (24) with a detector (25). The signal is transformed into an expression of the component of displacement in the direction of measurement (parallel to the plane of the drawing). The navigation system of the vehicle has as many velocimeters as there are co-ordinate axes in the frame of reference assigned to it. The measurement is made in a direction perpendicular to a line bisecting the angle between the two beams.
