Parallel subtraction of Fourier power spectrum using holographic interferometry.
We propose and demonstrate parallel subtraction of the Fourier power spectrum of two images with the use of real-time holographic interferometry. The subtraction, which exhibits shift invariance, is achieved by employing a Mach-Zehnder interferometer and a photorefractive crystal. The results are presented and discussed.
