Abstract
- Abstract: In a large collider experiment, the precision of the measurements is often limited by the knowledge of the location of the different sub-detectors which make up such an experiment. In A Large Ion Collider Experiment (ALICE), two such critical sub-detectors are the time projection chamber and the inner tracking system. Here is described a system which can monitor the relative position of these two sub-detector systems with the needed accuracy and within the space available. This system utilizes off the shelf USB web-cameras, diode laser light sources, and spherical mirrors. Tests have shown that it can provide a resolution of for displacements in the plane of the camera and about perpendicular to it. [Copyright &y& Elsevier]
