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.
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.
BK7 is a high quality optical glass suitable for use as holographic optical elements
, the initial target market for the product.
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.
