<p>The head (10) has a pitch frame (12) accommodating a detector component, and a yaw frame (14) formed as a ball section to pivotably support the pitch frame around an axis (N). A base (16) pivotably supports the yaw frame in another axis (G). The yaw frame is supported at the base over a rail (32). The rail and the yaw frame are partially extended around the latter axis such that the pitch frame has a pivot area of 180 degrees. A drive belt is connected with the yaw frame and a driving motor (44) such that rotating movement of a motor shaft is converted into pivoting movement of the yaw frame.</p> |
