Abstract
Recent studies of wave front conjugation have demonstrated several new features that are advantageous for optical imaging and adaptive optics. We present a detailed account of the wave front conjugation characteristics of nematic liquid-crystal films. These characteristics include extreme low cost, low optical power requirement, capability for large spatial frequency (and, therefore, image resolution), capability for fairly fast response (~0.2-msec rise and fall times), and capability for imaging with a spatially incoherent light.
