Holographic jewel
First Claim
1. A white light hologram jewel for jewelry, comprising:
- (a) a second generation Lippmann-Bragg hologram having an orthoscopic image of an object recorded therein, said image appearing on the viewer side of the hologram, said second generation hologram being made by using a psuedoscopic image reconstructed from a first hologram as the object for making said second generation hologram;
(b) a thick lens discrete from said hologram, bonded to and covering the viewer side of said hologram;
(c) said lens providing optical leverage in that a small tilt of the jewel relative to a read-out incident light beam causes a large spectral shift enhancing color change and amplifying the optical illusion of the object turning about a point in the jewel.

Abstract
A jewel and method of making same, the jewel being a unique hologram and lens combination. A reflection hologram of an object is first made and the psuedoscopic image is then used in recording a second generation hologram which permits reconstruction of the virtual image near or within the lens upon which the second generation hologram is located, usually being adhered thereto, the lens functioning to refract incident white light and enhancing spectral changes and brightness, while virtually eliminating the critical angle effect in the viewing of the jewel, and dramatically increasing the optical leverage or proportional magnification of apparent movement of the image for any given alteration in the incident light or viewing angle relative to the jewel.

10. A method of making a white light hologram jewel, comprising the following steps:
-
(a) making a Lippmann-Bragg hologram having a psuedoscopic image; (b) using said psuedoscopic image of the original hologram as an object for a second generation, Lippmann-Bragg hologram; (c) recording the image on a photosensitive medium as a second generation Lippmann-Bragg hologram; and (d) fastening the photosensitive medium on a thick viewing lens, whereby the secomd generation image exhibits apparent animation, under white light, upon relative movement of said lens and the incident angle of said white light and/or a viewer'"'"'s eye. - View Dependent Claims (11, 12, 13)
