A series of optical radars, for periodic inspection in fusion machines or more in general in any hostile environment, have been developed by the Italian National Agency for New Technologies, Energy and the Environment (ENEA). Those laser scanner systems are in general named In Vessel Viewing System (IVVS) and they comprise a mechanical probe, a Control and Data Acquisition System, and a customized Radar Electronic System [1]. In particular one of the IVVS systems was designed to be inserted inside an experimental nuclear fusion machine named JET. This IVVS needs an alignment system to correctly align the laser beam, coming from the passive module, to the scanning head. An alignment system based on two motorized mirrors with 4 degrees of freedom was developed. In this pape r are described the alignment system architecture, the geometrical solution of the problem and the relative semiautomatic alignment procedure.
