27 September 2007 Wave front transformation and correction by using SLM
Author Affiliations +
Wave front precision distortion correction and transformation using a Liquid Crystal Spatial Light Modulator (LC SLM) is discussed. After passing through non perfect elements, a coherent beam becomes a distortional beam. The distortion is expressed in either optical paths difference or phase difference way. The difference is measured quantitatively. SLM modulates the phase of the beam in a pixel resolution. The beam is recovered to a plane wave front again after the correction. The accuracy of the modulation is 0.0165λ.
