Numerical Implementation of the Homeomorphic Fourier Transform and its Application to Physical-Optics Modeling

Jena, 17 September 2019, EOS Topical Meeting on Diffractive Optics

The authors propose an efficient approach to perform the Fourier transform, which, even though approximated, is quite accurate under certain common conditions in optics: the “homeomorphic Fourier transform (HFT)”. We present the theoretical derivation and the numerical implementation. We illustrate its potential with examples.
