Appeal 2007-0203
Application 10/139,969
STATEMENT OF THE CASE
Appellants invented a system and method for effecting low-order
aberration correction of a beam of electromagnetic energy. In a preferred
embodiment, the invention comprises a telescope with a fixed primary lens
and a secondary lens moveable in multiple axes. The secondary lens is
moved responsive to aberrations detected by a wavefront error sensor to
compensate for the aberrations. See generally Specification 3:7-9; 10:28–
11:4; see also Fig. 3. Claim 22 is illustrative:
22. A method for effecting low-order aberration correction of a beam
of electromagnetic energy including the steps of:
receiving the beam using a telescope comprising a primary lens and a
secondary lens, said secondary lens being moveable in multiple axes;
generating a signal indicative of the aberrations to be corrected; and
adjusting the position of said secondary lens in response to said signal
to generate an output beam that is at least partially compensated with respect
to the aberrations.
