Three-dimensional wavefront engineering
We perform three-dimensional wavefront engineering to holographically reconstruct an arbitrary three dimensional (3D) optical structure. We divide the 3D structure into N layers of two-dimensional structures. We then calculate the holograms individually then apply the necessary phase to translate the reconstruction along the axial direction. Simulations were done to reconstruct a five layer toroid that was acquired from its corresponding g-code. We find that increasing the number of layers degrades the accuracy and quality of the reconstructions due to the effects of noise and plane crosstalk.
