Wavefront correction using micromirror arrays: Comparing the efficacy of tip-tilt-piston and piston-only micromirror arrays

Spahn, Olga B.; Sweatt, W.C.; Cowan, William D.; Wick, David V.

Micromirrors arrays can be used to correct residual wavefront aberrations in certain optical systems. The ability to correct Zernike aberrations using arrays of pistononly and arrays of piston-tip-tilt micromirror arrays are compared. Our micromirror fabrication program is discussed. © 2006 Optical Society of America.
