1.   The X-ray spectrometer thus directs a beam of X-rays at a crystal mounted on a turntable.

2.   A computer on the aircraft directs the beam by altering the synchronization of the individual radio waves generated by the antenna modules.

3.   The laser beam is directed in a full circle at the peripheral retina with the hope of stopping production of the chemical growth factor.

4.   The laser is now being tied to a system of big mirrors meant to focus and direct its beam so it could hit enemy missiles.

5.   They directed the beams at targets containing liquid hydrogen.
