Free Analog Computing with Imperfect Hardware” was published by researchers at The University of Hong Kong, University of ...

Then, the two-step methods based on the phase correlation and matrix-multiply discrete Fourier transform (DFT) algorithms are applied to register the sensed image to the reference subimage. Finally, ...

In this letter, we propose to realize optical discrete Fourier transform (DFT) and inverse discrete Fourier transform (IDFT) on one single multimode interference (MMI) coupler. In comparison to the ...
