ABSTRACT:
A method of designing a holographic optical element (diffractive grating) that transforms a set of waves into another set of waves in order to minimize aberrations in the phase of the output wavefront, includes the steps: (a) define continuous input parameters that characterize the propagation vector components of the incoming wavefront and the desired output wavefront; (b) formulate integral equations for the optimal grating vector components; and (c) solve the integral equations for the optimal grating vector components to minimize the difference between the actual and desired output wavefronts.
