There are various methods of producing laser shows; Laservision’s Excelsior laser animation software automates much of the process creating intermediate frames in real time between selected key frames. Alternatively, animation can be created in any other computer animation package or each frame can be individually drawn by an animator. Frames are then displayed in rapid succession to create the illusion of movement.

Certainly if you can guarantee the weather ! We recommend that a more reliable medium be used. Cloud projection can be considered a bonus when it is possible.

Most laser systems run on 3 phase power, this is readily available almost everywhere. A standard clean water supply is needed for cooling. Smaller laser projectors only need a standard domestic power supply and are cooled by an inbuilt fan or chillers not requiring any water.

Immersing the audience in a laser light show creates the ultimate in intense, laser atmospheric effects. This is called audience scanning. Laser power must be limited and the laser beam kept moving rapidly enough so that its' power is dissipated over a sufficiently large area. Projectors developed for audience scanning will be fitted with fail-safe beam-block devices to eliminate eye danger.

Each image is created and stored as a series of points, like a 'join-the-dots' picture. Two tiny mirrors mounted on scanners control high-speed beam movement and positions the laser beam on the screen. When all the points in a picture are scanned at least 25 times each second, then your eye perceives an image.

Laser light is visible only when it makes contact with a projection medium, this can be any non-reflective material or object either opaque or translucent. Light toned surfaces reflect light best, black is the least effective.

Artwork is copied from an existing image, created by hand or on a computer, and then saved as a special laser image file for replay into a spectacular laser show.

There are three main types of 3D laser illusions; Perspective 3D, Stereoscopic 3D and Aerial 3D effects. All 3D image projections viewed without special eyewear are, in reality, flat 2D images projected onto a screen. Stereoscopic 3D employs the technique used in film and print, two offset images projecting simultaneously are viewed through special eyewear and the brain interprets them as three-dimensional. 3D Aerial effects are truly three-dimensional, occupying space and engulfing an audience or venue in an architecture of light.

In theory an infinite distance, however airborne impurities and the beam’s divergence will eventually dissipate its power.

L.A.S.E.R = Light Amplification by Stimulated Emission of Radiation

Laser radiation is ‘visible light’, the non-ionising electro magnetic form that is around us all the time. It is no more dangerous than any other light source when controlled and in the hands of a professional.

Lasers produce fixed colours or light frequencies and can’t have their colour altered by placing gel filters in the beam. Krypton & Helium Neon lasers produce only red light, Argon lasers create cyan (blue & green} whilst mixed gas (Krypton & Argon together) emit white light made up of many light frequencies. Diode lasers produce either blue, red or green frequencies.

To produce a multi-colour display, you must first have all required colours present in the laser beam/s. Usually a mixed gas white light laser (that produces green, red, yellow & blue light).

Yes, any colour can be simulated with a white light laser and most shades in the green/blue spectrum with an Argon laser. Coloured laser light differs from printed pigments that reflect colour. The effect is purer and brighter than you are used to.

The Laservision projector's 'X-Window' is used to control each colour frequency allowing full spectrum projection. This Poly Chromatic Acousto Optic Modulator (PCAOM), is a solid state device that manipulates the brightness and mixes multiple laser colours.

The rules and regulations for public laser light shows and displays differ around the globe. When planning a public laser show Laservision can consult with the appropriate authorities in your region.

No. Display lasers are unsuitable for public laser shows; this still belongs to movie fantasy. Specialised high power lasers are used in industry to cut material but they are not used for display.

Not necessarily, however consider the venues ambient light level as all lighting and projection systems rely on contrast to be effective, and always avoid direct sunlight.

Laser projectors should generally be at least as far away as the screen’s longest dimension however some projectors can be placed hundreds of metres, or even kilometres, from the projection surface.

Like car headlights, a laser beam is perceived as brightest when directed toward an audience. Beams going away from the viewer have less apparent brightness. Beams that are perpendicular to the audience have much less intensity.

Laser shows that utilise animation and graphics production are generally cheaper than making a traditional video or film. A laser presentation has far more audience impact too. The projection equipment is more expensive to hire, but you get more ‘Wow Factor’ at your event!

There are a number of variations, water curtains that cascade and rows of individual fountain jets, the most effective for focused media like film, slide or video is the Water Screen a single high velocity ‘peacock tail shaped’ spray up to 30M in diameter. Ideal for laser show and video projection.
