IHMA Members Hear About It First!

The International Hologram Manufacturers Association (IHMA) is made up of the world’s leading hologram suppliers and manufacturers and as a benefit of membership they receive a range of services. Two examples are the Patent Newsletter and the Tender Alert Service.

Patent Newsletter

The IHMA Patent Newsletter is a monthly review of patents issued in the fields of security, decorative and data storage holography, along with holographic techniques, processes and displays.

In the ‘Security & Optical Effects’ category of April’s edition of the newsletter, Wavefront Technology discloses a method for fabricating masters and optical products.

The patent claims protection for an optical product comprising: an array of lenses; a first plurality of portions disposed under the array of lenses, individual ones of the first plurality of portions corresponding to a point on a surface of a first 3D object, and comprising first non-holographic features configured to produce at least part of a first 3D image of the first 3D object; a second plurality of portions disposed under the array of lenses, individual ones of the second plurality of portions corresponding to a point on a surface of a second 3D object, and comprising second non-holographic features configured to produce at least part of a second 3D image of the second 3D object; and an interference optical structure disposed with respect to said first and/or second non- holographic features.
