Laser Harp
A laser harp is an electronic musical user interface and laser lighting display. It projects several laser beams played by the musician by blocking them to produce sounds, visually reminiscent of a harp. It was popularised by Jean-Michel Jarre, and has been a high-profile feature of almost all his concerts since 1981. The laser harp became famous in Asia by Japanese artist Susumu Hirasawa. Invention French composer Bernard Szajner applied to patent the laser harp in 1981. It was granted in 1982, meaning that the French patent office had found no evidence of another inventor of the same or similar instrument before him. However, Australian inventor Geoffrey Rose claims to have taken out a provisional patent with the United Kingdom's patent office in 1975–1976, and his invention may have been shown and used as early as 1976. Design Framed style The framed style, which is often created to look like a harp with strings, uses an array of photodiodes or photoresistors inside th ...

Laser Harp NovaYA (7)
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 ...

Ultrasonic Transducer
Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters, receivers and transceivers. Transmitters convert electrical signals into ultrasound, receivers convert ultrasound into electrical signals, and transceivers can both transmit and receive ultrasound. Applications and performance Ultrasound can be used for measuring wind speed and direction (anemometer), tank or channel fluid level, and speed through air or water. For measuring speed or direction, a device uses multiple detectors and calculates the speed from the relative distances to particulates in the air or water. To measure tank or channel liquid level, and also sea level (tide gauge), the sensor measures the distance (ranging) to the surface of the fluid. Further applications include: humidifiers, sonar, medical ultrasonography, burglar alarms, non-destructive testing and wireless charging. Systems typically use a ...

Rendez-Vous (Jean Michel Jarre Album)
''Rendez-vous'' (English: Appointment) is the eighth studio album by electronic musician and composer Jean-Michel Jarre released on Disques Dreyfus, licensed to Polydor, in 1986. The album art was created by long-time collaborator Michel Granger. Composition and recording ''Rendez-Vous'' was created over a period of about two months. It features heavy use of the Elka Synthex, notably so on "Second Rendez-Vous", a track Jarre often performs using a laser harp. As with ''Zoolook'', it contains elements from the album ''Musique pour Supermarché'', in this case it is in "Fifth Rendez-Vous". The last track on the album was originally scheduled to include a saxophone part recorded by astronaut Ron McNair on the Space Shuttle ''Challenger'', which would have made it the first piece of music to be recorded in space. However, on January 28, 1986, 73 seconds after lift-off, the shuttle disintegrated and the entire ''Challenger'' crew were killed. The track was later dedicated to Mc ...

Chromaticism
Chromaticism is a compositional technique interspersing the primary diatonic scale, diatonic pitch (music), pitches and chord (music), chords with other pitches of the chromatic scale. In simple terms, within each octave, diatonic music uses only seven different notes, rather than the twelve available on a standard piano keyboard. Music is chromatic when it uses more than just these seven notes. Chromaticism is in contrast or addition to tonality or diatonic and chromatic, diatonicism and modality (music), modality (the major scale, major and minor scale, minor, or "white key", scales). Chromatic elements are considered, "elaborations of or substitutions for diatonic scale members".Matthew Brown; Schenker, "The Diatonic and the Chromatic in Schenker's "Theory of Harmonic Relations", ''Journal of Music Theory'', Vol. 30, No. 1 (Spring 1986), pp. 1–33, citation on p. 1.

Diatonic And Chromatic
Diatonic and chromatic are terms in music theory that are most often used to characterize scales, and are also applied to musical instruments, intervals, chords, notes, musical styles, and kinds of harmony. They are very often used as a pair, especially when applied to contrasting features of the common practice music of the period 1600–1900. These terms may mean different things in different contexts. Very often, ''diatonic'' refers to musical elements derived from the modes and transpositions of the "white note scale" C–D–E–F–G–A–B. In some usages it includes all forms of heptatonic scale that are in common use in Western music (the major, and all forms of the minor). ''Chromatic'' most often refers to structures derived from the twelve-note chromatic scale, which consists of all semitones. Historically, however, it had other senses, referring in Ancient Greek music theory to a particular tuning of the tetrachord, and to a rhythmic notational convention in me ...

Octave
In music, an octave ( la, octavus: eighth) or perfect octave (sometimes called the diapason) is the interval between one musical pitch and another with double its frequency. The octave relationship is a natural phenomenon that has been referred to as the "basic miracle of music," the use of which is "common in most musical systems." The interval between the first and second harmonics of the harmonic series is an octave. In Western music notation, notes separated by an octave (or multiple octaves) have the same name and are of the same pitch class. To emphasize that it is one of the perfect intervals (including unison, perfect fourth, and perfect fifth), the octave is designated P8. Other interval qualities are also possible, though rare. The octave above or below an indicated note is sometimes abbreviated ''8a'' or ''8va'' ( it, all'ottava), ''8va bassa'' ( it, all'ottava bassa, sometimes also ''8vb''), or simply ''8'' for the octave in the direction indicated by placing ...

Laser Projector
A laser projector is a device that projects changing laser beams on a screen to create a moving image for entertainment or professional use. It consists of a housing that contains lasers, mirrors, galvanometer scanners, and other optical components. A laser projector can contain one laser light source for single-color projection or three sources for RGB (red, green, and blue) full color projection. Lasers offer potentially brighter projected images, with more and better colors. Types of laser projectors * Industrial Laser Projectors are used as a guide, like a stencil in various manufacturing processes. * Home entertainment Laser Projectors have a wider color gamut and longer life. Industrial Laser Projectors The industrial laser projectors are on the market since about 2002/2003. Laser projectors are mainly used as optical guidance systems. They enable working without templates in many manufacturing processes by showing directly on the workpiece how material needs to be p ...

Camera
A camera is an Optics, optical instrument that can capture an image. Most cameras can capture 2D images, with some more advanced models being able to capture 3D images. At a basic level, most cameras consist of sealed boxes (the camera body), with a small hole (the aperture) that allows light to pass through in order to capture an image on a light-sensitive surface (usually a Image sensor, digital sensor or photographic film). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, and the aperture can be narrowed or widened. A Shutter (photography), shutter mechanism determines the amount of time the photosensitive surface is exposed to the light. The still image camera is the main instrument in the art of photography. Captured images may be reproduced later as part of the process of photography, digital imaging, or photographic printing. Similar artistic fields in the moving-image camera dom ...
