Ivan Dryer
Ivan Dryer (March 7, 1939 - July 27, 2017) is generally considered to be the father of the commercial laser light show industry. He is the founder of the world's first continuously running laser entertainment, known as Laserium. Dryer was a filmmaker in the early 1970s. On one project, he worked with Dr. Elsa Garmire, a California Institute of Technology physicist interested in laser light art. (She had previously worked with other artists on special event laser shows.) Dryer was disappointed because the resulting film, ''LaserImage'', did not have the pure colors and shimmer of laser light. Dryer realized that it was possible only to capture the special beauty of laser light by using the light itself, not in film or video form. Dryer had the idea of bringing the Caltech laser to Los Angeles' Griffith Observatory. He, Garmire and Dale Pelton formed Laser Images, Inc. to create Laserium laser light shows to be presented in planetariums. ("Laserium" is not a generic term; it is a reg ...

Laser Lighting Display
A laser lighting display or laser light show involves the use of laser light to entertain an audience. A laser light show may consist only of projected laser beams set to music, or may accompany another form of entertainment, typically musical performances. Laser light is useful in entertainment because the coherent nature of laser light allows a narrow beam to be produced, which allows the use of optical scanning to draw patterns or images on walls, ceilings or other surfaces including theatrical smoke and fog without refocusing for the differences in distance, as is common with video projection. This inherently more focused beam is also extremely visible, and is often used as an effect. Sometimes the beams are "bounced" to different positions with mirrors to create laser sculptures. Function Scanning Laser scanners reflect the laser beam on small mirrors which are mounted on galvanometers to which a control voltage is applied. The beam is deflected a certain amoun ...

California Institute Of Technology
The California Institute of Technology (branded as Caltech or CIT)The university itself only spells its short form as "Caltech"; the institution considers other spellings such a"Cal Tech" and "CalTech" incorrect. The institute is also occasionally referred to as "CIT", most notably in its alma mater, but this is uncommon. is a private research university in Pasadena, California. Caltech is ranked among the best and most selective academic institutions in the world, and with an enrollment of approximately 2400 students (acceptance rate of only 5.7%), it is one of the world's most selective universities. The university is known for its strength in science and engineering, and is among a small group of institutes of technology in the United States which is primarily devoted to the instruction of pure and applied sciences. The institution was founded as a preparatory and vocational school by Amos G. Throop in 1891 and began attracting influential scientists such as George Ellery H ...

Griffith Observatory
Griffith Observatory is an observatory in Los Angeles, California on the south-facing slope of Mount Hollywood in Griffith Park. It commands a view of the Los Angeles Basin including Downtown Los Angeles to the southeast, Hollywood to the south, and the Pacific Ocean to the southwest. The observatory is a popular tourist attraction with a close view of the Hollywood Sign and an extensive array of space and science-related displays. It is named after its benefactor, Griffith J. Griffith. Admission has been free since the observatory's opening in 1935, in accordance with the benefactor's will. Over 7 million people have been able to view through the 12-inch (30.5 cm) Zeiss refractor since the observatory's 1935 opening; this is the most people to have viewed through any telescope. History On December 16, 1896, of land surrounding the observatory was donated to the City of Los Angeles by Griffith J. Griffith.

Registered Trademark
The registered trademark symbol, , is a typographic symbol that provides notice that the preceding word or symbol is a trademark or service mark that has been registered with a national trademark office. A trademark is a symbol, word, or words legally registered or established by use as representing a company, product or service.For example, Unregistered trademarks can instead be marked with the trademark symbol, , while unregistered service marks are marked with the service mark symbol, . The proper manner to display these symbols is immediately following the mark; the symbol is commonly in superscript style, but that is not legally required. In many jurisdictions, only registered trademarks confer easily defended legal rights. In the US, the registered trademark symbol was originally introduced in the Trademark Act of 1946. Because the symbol is not commonly available on typewriters (or ASCII), it was common to approximate it with the characters (or ). An example of a ...

Los Angeles
Los Angeles ( ; es, Los Ángeles, link=no , ), often referred to by its initials L.A., is the largest city in the state of California and the second most populous city in the United States after New York City, as well as one of the world's most populous megacities. Los Angeles is the commercial, financial, and cultural center of Southern California. With a population of roughly 3.9 million residents within the city limits , Los Angeles is known for its Mediterranean climate, ethnic and cultural diversity, being the home of the Hollywood film industry, and its sprawling metropolitan area. The city of Los Angeles lies in a basin in Southern California adjacent to the Pacific Ocean in the west and extending through the Santa Monica Mountains and north into the San Fernando Valley, with the city bordering the San Gabriel Valley to it's east.

International Laser Display Association
The International Laser Display Association (ILDA) is the worldwide non-profit trade association and is dedicated to advancing the use of laser displays in art, entertainment and education. It was founded in August 1986. ILDA sponsors an annual conference and the annual ILDA Awards for artistic and technical achievement in laser shows and displays. While increasing public awareness of laser light shows, the ILDA is also an association that provides a base for laser display companies. The ILDA does not perform laser light shows itself, but its members primarily consist of laser light show hosts or companies that sell equipment and services. Members of the company can work with each other, not as competitors, but as colleagues with whom they can collaborate. Being associated with ILDA, members can have professional backing that will supply information on new technologies regarding safety issues and improved display performance. ILDA History ILDA was founded on August 16, 1986, at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Visual Music Artists
The visual system comprises the sensory organ (the eye) and parts of the central nervous system (the retina containing photoreceptor cells, the optic nerve, the optic tract and the visual cortex) which gives organisms the sense of sight (the ability to detect and process visible light) as well as enabling the formation of several non-image photo response functions. It detects and interprets information from the optical spectrum perceptible to that species to "build a representation" of the surrounding environment. The visual system carries out a number of complex tasks, including the reception of light and the formation of monocular neural representations, colour vision, the neural mechanisms underlying stereopsis and assessment of distances to and between objects, the identification of a particular object of interest, motion perception, the analysis and integration of visual information, pattern recognition, accurate motor coordination under visual guidance, and more. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laser Art
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light which is ''coherent''. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers and lidar (light detection and ranging). Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum. Alternatively, temporal coherence can be used to produce ultrashort pulses of light w ...
