Patent ID: 8503052

Claim:
A modular master hologram stack comprising: a holder configured for interchangeable support of at least two multichannel image generation devices, a reservoir to contain refractive index matching fluid between said multichannel image generation devices, a support for at least one three-dimensional (3D) object or hologram of a 3D object beneath said multichannel image generation devices; wherein the modular master hologram stack is configured to record a holographic image onto holographic recording film, said holographic image comprising a hologram of a 3D object in conjunction with a multi-channel holographic image, the method comprising: forming a holographic recording stack by: positioning said holographic recording film over said multichannel image generation device; positioning said at least one 3D object or hologram of a 3D object under said multichannel image generation device; and providing a transparent window in said multichannel image generation device in a region above said at least one object; and then recording said holographic image in said holographic recording film by illuminating said stack through said holographic recording film with a laser light of at least one wavelength.
