This can be done through the use of customized Holographic Optical Elements (HOE) as one developed by LighTrans [14] (see figure 13).
Unfortunately Intrepid Global Images also failed, but not before it had been granted one patent (US 8,284,234, Endoscopic imaging using reflection holographic optical element for autostereoscopic 3-0 viewing) and had applied for several US and WIPO patents, covering its innovations in autostereoscopic imaging.
The IHMA says the award categories cover the full end-to-end spectrum of holographic techniques in origination, production and finishing, with the awards to showcase the best examples of design, artwork and techniques used in holographic origination to the application of holographic optical elements, for example In display screens, lighting, communications and vehicular systems.
Using the same laser light interactions that are used to create holograms that protect credit cards from forgery, it is also possible to fabricate holographic optical elements (HOEs) such as lenses and filters in light-sensitive materials.
These are generated using 3D computer aided design (CAD) software prior to being originated and combined with 100 x 100 micrometers holographic optical elements (HOEs).
Holographic optical elements (HOE) are another area where IHMA has predicted increased activity.
We now have holographic optical elements in head up displays (HUD) from Luminit, holographic buttons, holographic microscopes, holography being used in dentistry, holograms being used on Bltcoins, Microsoft's HoloLens, Google Glass and its associated developments, holographic storage and so on.
We see security, packaging and holographic optical elements (HOEs) as our target markets, where high volume requirements are coupled with decent margins for the right materials.
