Abstract

CHIMERA is the third generation of digital holographic printing system based on three low-power continuous lasers combined with Ultimate U04 silver-halide holographic glass plates. This holoprinter prints at 50 Hz, 120° full-parallax, and full-color digital reflection holograms or holographic optical elements with a size of up to 60×80 cm and a 250 μm hogel size. An in-house scanner was designed to record full-parallax CHIMERA holograms of still object scenes. This scanner can automatically record a still object scene from 10×13 cm to 60×80 cm with a 4K camera and a controlled turning table. The scanner records a still object scene in 2 hours with 768 horizontal images, 192 elevation levels, and a 180 degrees rotation. From the obtained perspective images, in-house software calculates all the hogels for the CHIMERA printing. This paper discusses the different characteristics of this in-house scanner and analyzes its advantages, benefits, and limitations for applications such as museums, art, education, architecture, and advertising.
