Laser Beam Steering System
An optical steering system is disclosed which simplifies the alignment of
laser beams by allowing the beam to emerge within a bounded conical volume
with a selective angular displacement.
The steering device consists of two confocal, face-to-face microscope
objectives, one being stationary and fixed in a mount and the other being free to
swivel on a perforated ball which rides on a spherical socket in the first objective
As shown in the figure, the stationary objective 1 includes the spherical
socket 2 in which is pivotally mounted the perforated ball 3 of the pivotable
objective 4. The optical elements of each microscope objective are positioned so
that their respective focal points 6 are coincident. If the pivotable objective 4 is
rotated or tilted about the common optical axis 5 along which a laser beam is
incident, the laser beam 5' issuing from the pivotable microscope objective 4 can
be displaced through an angle of +/-30 degrees, with respect to the incoming
optical axis 5, in all directions.
As the laser beam diverges at 7 from the focal point 6, it must fall within the
entrance pupil 8 of the pivotable objective 4 in order to exit from the objective 4
parallel with the optical axis 9. Thus, a larger angle of deflection can be achieved
by using an objective 4 with a larger entrance pupil 8.
The resulting steering system simplifies the alignment of laser beams by
allowing the beam to emerge in any one direction within a so...
