light valve การใช้

• Liquid crystal light valves work by rotating light between two polarizing filters.
• BSO crystals are used in optically addressed spatial light modulators and in liquid crystal light valves.
• This type of valve is often referred to as a " liquid crystal light valve ".
• Light valves then vary the amount of light reaching the eye, by blocking its passage in some way.
• Our windows act like light valves,
• The first LCOS device originated in 1973, followed by a development of a liquid-crystal light valve ten years later.
• In 1927, Vsevolod Frederiks devised the electrically switched light valve, called the Fr閑dericksz transition, the essential effect of all LCD technology.
• The Western Electric system continued to use the " light valve ", and, under successor ownership, is still used to this day.
• SCIENTIFIC AND TECHNICAL AWARD : Gunnar P . Michelson, developer of an advanced electronic light valve for machines that strike movie prints.
• Examples of the reflective LV type are the Digital Micromirror Device ( DMD ), Eidophor's oil-film based system, and the Grating Light Valve.
• In 1936, the Marconi Wireless Telegraph company patented the first practical application of the technology, " " The Liquid Crystal Light Valve " ".
• The light valve thus consists of the two polarising filters, where one has a voltage controlled switch function thanks to the properties of the liquid crystals.
• Light from a Xenon arc lamp was modulated by a light valve consisting of a rotating glass disc that was continuously re-coated with a viscous oil.
• Silicon Light Machines ( SLM ), in Sunnyvale CA, markets and licenses GLV technology with the capitalised trademarks "'Grated Light Valve "'and GLV, previously Grating Light Valve.
• Silicon Light Machines ( SLM ), in Sunnyvale CA, markets and licenses GLV technology with the capitalised trademarks "'Grated Light Valve "'and GLV, previously Grating Light Valve.
• The idea was to use elements referred to as " light valves " to regulate the amount of light that passes through it, such as in traditional slide projectors.
• After several tests, Woodland said that Dan's Camera City, which has two Noritsu systems from Kodak, settled on something called a Micro Light Valve Array, in which light from a halogen bulb passes through computer-controlled filters and is transferred to the photographic paper through optical fibers.
• In the mid-1970s Westrex Corp . ( a wholly owned subsidiary of Litton Industries since 1956, and the successor to Western Electric's cinema sound business unit ) re-introduced the ca . 1938 " four ribbon " light valve, and the ca . 1947 RA-1231 sound recorder.
• On March 10, at a meeting of the National Association of Theater Owners, two new electronic projectors _ one by Texas Instruments that relies on a chip with more than a million tiny mirrors, and a competing technology using what is called a light valve produced by Hughes-JVC _ will demonstrate what they can do.
• Simpson was also motivated by a 1967 book in which former president of CBS News Fred Friendly was quoted as having said,  for the most part we were . . . just a bunch of old radio hands learning the hard way that cameras need something more than emulsion and light valves to create electronic journalism.
