Holography seems to have a limitless number of applications in industry, science, business and education. For example:

• Double-exposed holograms provide heat-transfer data for the safe design of containers that transport or store nuclear materials.
• Holograms on credit cards carry a monetary value. A scanner can read the amount, deduct the cost of an item and leave the new amount on the card.
• The aircraft industry uses holography to depict the shock wave made by air foils to locate the areas of highest stress -- information critical to the improvement of aircraft wings and turbine blades.
• A holographic lens in an aircraft "heads-up display" allows a fighter pilot to see critical cockpit instruments while looking straight ahead through the wind screen. Similar systems are in development for cars and trucks.
• Holography is ideal for archival recording of valuables or fragile museum artifacts. Curators used a hologram to catalog a 2300-year-old Iron Age man unearthed from a peat bog in Cheshire, England; the Forensic Science Department of Scotland Yard used the hologram to study the body.
• Optical computers, which use holograms as storage material for data, might someday be able to deliver trillions of bits of information faster than the current generation of computers.
