  • Hologram technique for establishing the integrity of packages
    Patent number: 4200394
    Abstract: A technique for detecting whether a package has been tampered with or altd. A package is first coated with a transparent material, such material having bubbles or particles of random size and/or spacing trapped within it. A hologram is then made of the package with the bubbled coating, showing the spacial relationship of the surface of the package and the bubbled coating. At the destination of the package, the package is viewed through the hologram to detect any change in the spacial relationship between the package surface and the bubbled coating. Any such change in the spacial relationship would indicate that the package had been tampered with or altered.
