The 6 m2, 8 plane Si tracker of the AMS-02 experiment can record charged particles from the cosmic radiation with high precision. The single hit resolution transverse (parallel) to the magnetic field is σy 8.5 μm (σx, 30 μm). AMS will measure with unprecedented resolution cosmic particles in a near earth orbit. The AMS-tracker is equipped with a position control system based on pulsed infrared Laser beams, that are directly seen by the Si sensors of the tracker, allowing to detect lateral displacements of less than 5 μm. The diffraction of the Laser light at the read out structure of the Si sensors does generate clearly visible patterns. It will be demonstrated that changes in the relative separation of these diffraction fringes can be used to determine the distance between layers (depth z) of the AMS tracker with a precision of 100 μm.
