Abstract
We introduce the novel parallel-aligned liquid crystal wavefront corrector (LC WFC) with 1920×480 pixels designed to operate at phase-only mode. The optical characteristics of the LC WFC were measured. The theory of diffractive optics is used to correct the aberrated wavefront. The measured peak-valve (PV) value of the wavefront is 9.956λ before correction and 0.837λ after that. Moreover, the measured root mean square (rms) value of the wavefront is 2.202λ before correction and 0.124λ after that. It expands LC devices' application fields.
