Abstract :
A numerical image reconstruction technique is proposed, where the images are calculated by performing a Fourier transform once instead of transforming twice as in the conventional method. This technique enables us to reconstruct images from off-axis holograms. An image reconstruction experiment was done with a sound-wave hologram of 18 kHz.
