This can be done through the use of customized Holographic Optical Elements
(HOE) as one developed by LighTrans  (see figure 13).
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.
The specific End-use segments analyzed are Holographic Scanning, Holographic Industrial Testing, and Holographic Optical Elements
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.
Wavefront had built a 12" web embossing machine designed specifically for small runs, on which they were producing holographic optical elements
(HOE's), diffusers and transmission gratings.
The two new patents cover a technique for using holographic optical elements
to greatly simplify the design of FSO transceivers and a device for measuring the attenuation characteristics of building windows during the deployment of FSO and MMW systems.
Holographic optical elements
are advancing the quality of displays and meeting the performance and cost demands of the fast-paced information technology industry.
Initially, DigiLens is targeting the rapidly emerging handheld PC and wearable display marketplaces by combining DuPont's Holographic Optical Elements
(HOEs) with DigiLens' Application Specific Integrated Lens (ASIL).
BK7 is a high quality optical glass suitable for use as holographic optical elements
, the initial target market for the product.
Using DigiLens technology is similar to using industry-standard DuPont holographic photo polymers for making Holographic Optical Elements
(HOE)--only with DigiLens, the resultant optical ASIL is multi-layered, individually addressable and able to switch clear," noted Sagan.
Papers are as diverse as Kurz's latest holograms for banknotes to Morphotonix' methods for making surface-relief chocolate moulds, or the use of holographic optical elements
in vehicles to DiArts new origination system.
This, of course, excludes holographic optical elements
, 2D visual holograms, interferometric and data storage holograms.
