Abstract
We demonstrate a simple holographic technique that allows for enlarging
the holographic image at the reconstruction
stage. It employs a spherical mirror for generating an image
that straddles the hologram to obtain the maximum of depth.
The holographic image is projected by using a white-light reconstruction
beam, a lens and a transmission diffractive screen to an enlargement
of up to 25 times the area of the original image. Wavelength
encoding of views is the new process that projects the holographic
image by using all the visible spectrum, low f
number lenses and allows for 18 simultaneous
observers.
