Abstract
We theoretically and numerically investigate the optical implementation of the second-order spatial differentiation operation using a layered metal-dielectric structure at normal light beam incidence. Numerical simulation results confirm the theoretical results and show the possibility of ‘optical calculation of the Laplace operator with high quality.
