Abstract

CHIMERA is the third generation of digital holographic printing systems. CHIMERA is based on the use of three lowpower red, green, and blue continuous lasers combined with the Ultimate U04 ultra-fine grain silver-halide holographic glass plates. Acquisition of perspective images can be done with an in-house designed cylindrical scanner for real still objects or with software for computer-generated objects. This holoprinter is capable of printing at a frequency equal or greater than 50 hogels per second, full-color, 120° full-parallax digital reflection holograms or holographic optical elements with a size of up to 60×80 cm and a hogel size ranging from 250 to 500 μm. The color rendition and the parallax—horizontal and vertical—of this printer are so good that, with a 250 μm hogel size, an observer can hardly detect a difference between an analog ultra-realistic full-color Denisyuk hologram and a digital CHIMERA hologram. This paper discusses and compares the different characteristics of the two techniques—CHIMERA and Denisyuk—for still object recording and analyzes their advantages, benefits, and limitations.
