<P>PROBLEM TO BE SOLVED: To provide a scanning station which has a simple configuration and is easy to handle. <P>SOLUTION: A radiation director 24 is coupled to move under the control of a piezoelectric element 2. The director directs electromagnetic radiation 20 from a radiation source 22 under the control of the piezoelectric element. In a scanning station embodiment, an electrical signal element 12 is connected to cause the piezoelectric element to vibrate, and a radiation director 32 is positioned to detect radiation from an object scanned by the radiation. In a radiation scanning method, the piezoelectric element is caused to move in a reciprocating fashion, and the movement of the piezoelectric element is used to direct an electromagnetic radiation beam in a scanning motion. <P>COPYRIGHT: (C)2003,JPO |
