Denisyuk-type wavefront printer and its computational correction of aberration in optical system

In a Denisyuk-type wavefront printer that features direct printing of wavefronts without any power loss, a novel technique is presented for computational correction of aberrations caused by alignment errors. In this technique, the position of the reconstructed image is corrected by numerically multiplying a lens phase by the wavefield produced by the spatial light modulators. The proposed technique has the advantage that aberrations caused by axial alignment errors can be canceled without additional physical adjustments to the optical system. To validate the proposed technique, we fabricated largescale computer-generated volume holograms (CGVH), over 12 cm square, using the Denisyuk-type wavefront printer developed in this study.
