Abstract: A method and system provide the ability to measure relative displacement and rotation. A first light is continuously shined from a first light source that is fixed on a first entity to a first two-dimensional (2D) plate fixed on a second entity. The first direction of propagation of the first light does not change relative to the first entity. A second light is shined from a second light source that is fixed on the first entity to a second 2D plate fixed on the second entity. A second direction of propagation of the second light does not change relative to the first entity and is different from the first direction of propagation. The displacement of the lights on plates is directly monitored to determine a 3D displacement vector that represents a relative displacement between the first entity and the second entity. Thus, a three dimensional gravity gradient tensor is constructed.
