Author Affiliations +
We analyze the scattering field generated by the coherent illumination of a three-dimensional transmittance characterized by a slit-shape curve. Generic features are obtained by using the Frenet-Serret equations which allows a decomposition of the scattering field. The analysis is performed by describing the influence of the curvature and torsion on osculating, normal and rectifying planes. Focusing and bifurcation effects are predicted and corroborated experimentally.
