Two-step astigmatic rainbow holograms projecting real images in front of the hologram

A new kind of rainbow holography, called real-image astigmatic rainbow holography, is presented. Differing from conventional astigmatic rainbow holography, which has images behind the hologram, this new holography can project a real image distinctly in front of the hologram.
