Applications of Holography Holography is an immensely versatile medium, both in the underlying technology and in the applications for which the output of the technology can be used. Many No of Industries used Holography for the Purpose of Authenticity of product and decorative packaging. For Document and product protection now one can with latest Track N trace technology incorporated with Holographic element Such as 3D QR Code and data input will be his website address and even Photograph of Individual is possible now a days. Security Hologram is visual data storage. For packaging and promotional purposes, the versatility of holographic products, which can supplied in a wide variety of designs, materials and format to integrate with existing packaging design and production processes, are providing stunning visual effects way beyond the capabilities of conventional techniques for pack enhancement and brand differentiation. As a result, holographic materials have consistently and repeatedly performed successfully, delivering above-target performance to customers and adding percentage points to market share. In the retail environment, holograms attract attention as eye-catching items for giftware, gift-wrap and stationery, as well as in-store décor, while the same visual appeal and novelty value is promoting growing markets for the use of holography as a display medium. Finally, a new and growing area for holography is in so-called industrial applications, where the manipulation of light is opening up new markets in display and instrumentation enhancement, lighting, architectural and interior design, data storage, diagnostics and medical imaging, Holographic Projection, Holoshowcases, Holostage , 3D visualisation, modelling and mapping, and interferometry.
