title: Rainbow holography with large image depth.
abstract: A synthetic slit method is used to record the rainbow hologram of a three-dimensional diffused object directly, without any lens. By controlling the position of the synthetic slit, we use this method to produce the reconstructed image of a hologram with much larger image depth than without such control.
