Abstract
A simple and reliable novel method providing the ability to measure the spatial relative displacement and rotation of objects as well as the measurement of the different degrees of freedom of each object (i.e. rotations and translations) relative to an inertial frame. This novel technique relies on the measurement of the center of an energy pattern emanating from a source to a detector. Our technique can be used in diverse applications like remote sensing, as it applies to earth/planetary and geo sciences, oil/gas exploration, and mining, civil, structural, medical engineering, and homeland security & defense, among others.

1. A method for measuring displacement and rotation, comprising:
A network of objects composed of (one, two or many more) objects. From an object acting as a source emanates an energy beam pattern travelling toward another object, which acts as a detector. At the detector, the position of the center of the pattern of the beam of energy is measured and hence its position relative to the detector is measured using centroid algorithms. Thus the projection of the displacement of the source relative to the detector on the plane of the detector is measured. Following this line of thought the three dimensional relative displacement could be measured if another energy beam pattern emanating from the source at a different angle or the same energy beam but received at another angle at the detecting is monitored. The combination of the two latter measurements yields to deduce the three dimensional motion of the source relative to the detector. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11)

12. We claim a network of objects or stations performing the measurement of relative displacement and rotations between the stations or objects using the technique we introduced. The network is composed of unit stations or objects, as depicted in
FIG. 15 . It could be either composed of one, two or many more objects. One could envisage that the network is composed of homogenous unit stations as depicted inFIG. 2(a) but we also expect to have a hybrid inhomogeneous network. Each station or object of the network could be located either on a moving object such as (satellites, airplanes, balloons, or cars, or others etc. . . . ) or static, like stations on the ground, or composed of both moving and static objects. Each station or object of the network could be located underground, under sea, on ground, on sea in air or in space. Each one of them could be static or mobile and different that the others.
