The space-bandwidth product in the joint transform correlator optical encryption setup
(Elsevier Science, 2011-09-01)
In this work we study the joint transform correlator (JTC) optical encryption setup through the Wigner function. We found analytical expressions for the spatial and spatial frequency extent of the encrypted signal. Since ...
Joint transform correlator optical encryption system: Extensions of the recorded encrypted signal and its inverse Fourier transform
(Elsevier Science, 2015-05)
In this work we study the joint transform correlator setup, finding two analytical expressions for the extensions of the joint power spectrum and its inverse Fourier transform. We found that an optimum efficiency is reached, ...
