Paper Abstract

An algorithm is presented for the computation of large size fast Fourier transforms (FFTs) for computer-generated holograms. The algorithm is useful when the recording device has a very large space-bandwidth product and the computation is under memory restrictions. The number of complex operations required using this algorithm is slightly larger than the number of operations necessary using the FFT algorithm.
