Claim Text:
1. A method for processing an input beam in a self-referencing interferometer to improve quality of the input beam, the method comprising: receiving at the interferometer the input beam; splitting with a beam splitter the input beam into a reference beam and a signal transmitting the reference beam through a single mode fiber to reduce aberrations in the reference beam; recombining the reference beam and the signal beam by transmitting the reference beam and the signal beam through a combining prism system; introducing a relative tilt between the reference beam and the signal beam by the combining prism system prior to recombining at a wave front sensor camera, wherein a magnitude of the relative tilt is controlled by adjusting a relative separation of the focal spots of the reference and signal beams on a combining prism of the combining prism system by linearly translating the combining prism in one of two directions; modifying the recombined reference beam and signal beam by transmitting the combined reference beam and signal beam through an anamorphic optical relay; and receiving the modified, recombined reference beam and signal beam at the wave front sensor camera; identifying, by a computing device coupled to the wave front sensor camera, an aberration in the signal beam; and controlling a spatial light modulating device to correct the identified aberration in the signal beam.
