Paper Abstract
In CGH, peculiar rendering techniques are necessary to express realistic 3D images because CGHs have parallax.
We have proposed the calculation method with the ray tracing method that expresses the hidden surface removal,
shading and so on. However, resolutions of current output devices are not high enough to display CGH, so the
size of reconstructed images is restricted and viewing zone and visual field are very narrow. To enlarge the size
of reconstructed images, the Fourier transform optical system is used. Then we introduce the technique to apply
calculation method of CGH with ray tracing method to the Fourier transform optical system in this paper. The
Fourier transform optical system reverses the depth of images and reconstructs pseudo stereoscopic 3D images
in front of a hologram. We solved this problem by reconstructing images at the back of hologram plane and
observing conjugate images. Moreover, we conducted elimination of unnecessary light including 0-th order light.
We conducted optical reconstructions that show proposed method is able to make realistic CGHs implementing
the hidden surface removal in the Fourier transform optical system.
