Abstract: Method and apparatus for constructing and reconstructing a hologram, whereby the hologram is reconstructed upon the original image plane used in constructing the hologram, by use, in one embodiment, of a spherical mirror placed to reflect divergent light originally passing through the hologram, back through the hologram as convergent light. Included are liquid gate means for reducing reflection glare from the hologram onto the reconstructed image.
