Abstract
We review some earlier work on parallel image subtraction and present new experimental results on shift-invariant parallel subtraction of the Fourier power spectrum of two images. The subtraction is achieved by employing a real-time holographic Mach-Zehnder interferometer with a photorefractive crystal.
