1.What is front-projected holographi c display? Front-projected holographic display, also known as virtual imaging technology, is a recording and reproducing tech nology that records and reproduces the real three-dimen sional images of objects using interference and diffractio n principles. 2 How to Realize Holographic Projection Technology? • As can be seen above, holographic projection imaging is mainly realized by using holographic projection film, which is an imaging medium with high lumen projector and optical technology. Holographic projection film is a new projection material. It uses a unique transparent projection material to achieve high-definition image. The final image effect is ...
Contents Introduction Magnetic and conventional optical data storage technologies are approaching physical limits beyond which individual bits may be too small or too difficult to store. Holographic data storage is an approach of storing information throughout the volume of a medium—not just on its surface. With the rapidly increasing demand for increased storage capacity in a smaller space, this technology offers an economy in price. Features Next – Next generation Technology 1 HVD = 5800 CDs = 830 DVDs = 160 Blu-ray Media type : Ultra-high density optical disc Encoding : MPEG-2, MPEG-4 AVC (H.264), and VC-1 Capacity ...
Holographic Optical Data Storage (HODS) or Holographic Data Storage System (HDDS) – The Revolutionary data storage technology – Uses images (holograms) rather than bits to store data – Images imposed in material – Uses a combination of Lasers & Optical materials to achieve this . – This is a Volumetric approach. Pieter J. van Heerden first proposed the idea of holographic (three-dimensional) storage in the early 1960s. A decade later, scientists at RCA Laboratories demonstrated the technology by recording 500 holograms in an iron-doped lithium-niobate crystal. The advent of Semiconductor & magnetic memories stalled its research for much time ...
Question 2 • 2. What hardware technology are you least concerned about for preservation archives in terms of reliability of the bits, and why. > Tape > Most of the digital archive data is on tape -> good track record. > There are still some customers with 3420s and 4480s out there, technology 20- 30 yrs old > Many independent studies done to predict archive life – 10 - 100 years – Manufacturers typically recommend 30 years maximum – Possible failure mechanisms Particle corrosion Binder and substrate aging Magnetic thermal stability > Consider technology ...
