Abstract

We have recently introduced a method based on a volume diffractive element (VDOE) to correct the coherence plane tilt in off-axis DHM. The VDOE consists of two phase gratings recorded on a photopolymer (BAYFOL^® HX) from Bayer MaterialScience AG, each laminated on one side of a wedge prism. The VDOE is placed in the reference arm of an off-axis DHM to introduce a small tilt γ in the coherence plane of the reference without any effect on the propagation direction.
