Abstract: Disclosed is a process for configuring a hologram (30) onto a final laminate (38) incorporating the hologram (30), including a car windshield or an aircraft canopy. The process includes first developing the hologram (30) on a process substrate (22). Intermediate the hologram (30) and the process substrate (22) is a thermoplastic layer (24). After the hologram (30) has been developed, the hologram laminate (20) including the process substrate (22), thermoplastic layer (24), and hologram (30) is applied to a first final laminate layer (34) by means of an adhesive (32) such that the hologram (30) is facing the first final laminate layer (34). Once this step is completed heat is applied to the hologram laminate (20) to melt the thermoplastic layer (24), thus removing the process substrate (22). Therefore, a second final laminate layer (40) can be applied to the opposite side of the hologram (30) without any drawbacks from the thickness of any additional support layers in the final laminate (38).

Abstract: The present invention comprises hologram combiners that incorporate one of several compositions of material to seal their perimeters and prevent the hologram from being attacked by water. The design of the combiner edge seals are fabricated using a perimeter edge buildup technique. The invention is implemented by the use of a band of polymer film, or a metal film such as aluminum foil, for example, that is adhered to the edge of periphery of the combiner. Adhesion is achieved by the use of a adhesive material that has been filled with a water absorbing material comprising molecular sieves such as crystalline aluminosilicate, zeolites, or calcium oxide. Calculations and accelerated static testing have indicated that the present invention provides for a hologram combiner that meets the most stringent environmental requirements, and is suitable for substantially all applications in which it may be employed.
