  Computer-generated holography (CGH) can be used to display three-dimensional
(3D) images and has a special feature that no other technology possesses: it
can reconstruct arbitrary object wavefronts. In this study, we investigated a
high-speed full-color reconstruction method for improving the realism of 3D
images produced using CGH. The proposed method uses a digital micromirror
device (DMD) with a high-speed switching capability as the hologram display
device. It produces 3D video by time-division multiplexing using an optical
system incorporating fiber-coupled laser diodes (LDs) operating in red, green,
and blue wavelengths. The wavelength dispersion of the DMD is compensated for
by superimposing plane waves on the hologram. Fourier transform optics are used
to separate the object, conjugate, and zeroth-order light, thus eliminating the
need for an extensive 4f system. The resources used in this research, such as
the programs used for the hologram generation and the schematics of the LD
driver, are available on GitHub.
