Curved Holographic Optical Elements from a Geometric View Point

We present a geometric framework to model the optical effects of deformations of planar holographic optical elements (HOE) into curved surfaces, such as sphere segments. In particular, we consider deformations which do not preserve the Gaussian curvature.

Curved holographic optical elements from a geometric view point: graphical visualization and parametric optimization

We present numerical experiments regarding the diffraction characteristics and their precompensation arising from changing the macroscopic geometry of a flat HOE into a sphere segment. In particular, we discuss a parametric optimization scheme using a grating vector field model which was previously introduced in Ref. 1.
