ABSTRACT:
Apparatus for detecting or measuring movements in geological and other formations and capable of carrying out such measurements on a three-dimensional basis. The apparatus has a housing acting as a support and an elongated arm, e.g., a stiff measuring rod of adjustable length, projecting from the housing and acting as a movement following element. One end of the rod is secured within the housing by sliding and pivoting connections so that the remote end of the rod may move freely in three dimensions relative to the housing. Three movement sensors are positioned within the housing. A first one of the sensors measures translational motion of the rod in the axial direction. A second sensor measures rotation of the rod about the pivot in a first plane. A third sensor measures rotation of the rod about the pivot in a second plane which intersects the first plane at right angles. The first movement sensor is preferably a linear potentiometer and the second and third sensors are preferably rotary potentiometers. The signals from the sensors may be subjected to mathematical transformations for conversion to spatial positions of the remote end of the rod, making it possible to detect and measure three-dimensional ground displacements.
