people watch movies. VHS’s successor‚ the DVD‚ was not quite as much of a game changer‚ but it still had a huge impact on the home video market. DVD came on the scene in the late 1990s‚ but the story actually begins in the early 1960s. In 1961‚ optical recording technology was patented by David Paul Gregg and James Russell. It wasn’t until the 70s that progress was seen on this front and in 1978 the Laserdisc format was released. Laserdisc was the major predecessor to DVDs‚ but it never really gained

NIGHT VISION TECHNOLOGY ABSTRACT A night vision device (NVD) is an optical installment that allows images to be produced in levels of light approaching total darkness. They are most often used by the military and law enforcement agencies‚ but are available to civilian users. The term usually refers to a complete unit‚ including an image intensifier tube‚ a protective and generally water-resistant housing‚ and some type of mounting system. Many NVDs also include sacrificial lenses‚ IR illuminators

Fiber Optics Fiber Optic Cable Facts "A relatively new technology with vast potential importance‚ fiber optics is the channeled transmission of light through hair-thin glass fibers." [ Less expensive than copper cables [ Raw material is silica sand [ Less expensive to maintain If damaged‚ restoration time is faster (although more users are affected) [ Backbone to the Information Superhighway Information (data and voice) is transmitted through the fiber digitally by the use of high

The first example is the Muller-Lyer illusion which is an optical illusion consisting of stylized arrows in which viewers tend to perceive one as longer than the other. The second example used is the Sanders Parallelogram in which a diagonal line bisecting the larger‚ left-hand parallelogram appears to be slightly

CDs and DVDs are the primary data storage methods for music‚ software‚ personal computing and video In order to increase storage capabilities‚ scientists are now working on a new optical storage method‚ called holographic memory that will go beneath the surface and use the volume of the recording medium for storage‚ instead of only the surface area. Holographic memory offers the possibility of storing 1 terabyte (TB) of data in a
