| 摘要 |
The present invention features an anamorphic apparatus (200) that alters a wavefront of a beam having a wavefront error to form a beam comprising a region having a greatly reduced wavefront error. A beam stop (240) may be used with the anamorphic apparatus to define a portion of the region having a greatly reduced wavefront error that is subsequently detected or launched into a fiber optic. Furthermore, the anamorphic apparatus (200) can be incorporated into an interferometry system to reduce errors associated with wavefront error and beam shear, i.e., non-cyclic non-linearities. |
