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.
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. [citation needed] While increasing public awareness of laser light shows, the ILDA is also an association that provides a base for laser display companies.
A projection keyboard is a form of computer input device whereby the image of a virtual keyboard is projected onto a surface: when a user touches the surface covered by an image of a key, the device records the corresponding keystroke. Some connect to Bluetooth devices, including many of the latest smartphone, tablet, and mini-PC devices with ...
However, since most laser show software uses a 0–100% control for laser brightness modulation (therefore 100 steps instead of 255), the total of available colors at disposal is only 1 million. Furthermore, usual laser sources start at a voltage between 1 and 2 volts and reach their full brightness at voltages between 3.5 and 4V, and the power ...
Box/Housing – a metal or plastic container to house the whole instrument and prevent light from spilling in unwanted directions. Light source . Lens or opening – the gap in the housing where the light is intended to come out. Reflector – behind or around the light source in such a way as to direct more light towards the lens or opening.
The image recognition laser harp is also an unframed design, but uses a high-speed USB camera connected to a laptop computer, instead of a photodiode to detect the reflected light from the hand breaking the beam. The digital picture is analysed by the computer software to determine which beam is broken and send the appropriate MIDI signal back ...
Optical computing or photonic computing uses light waves produced by lasers or incoherent sources for data processing, data storage or data communication for computing.For decades, photons have shown promise to enable a higher bandwidth than the electrons used in conventional computers (see optical fibers).
LightScribe is an optical disc recording technology that was created by the Hewlett-Packard Company.It uses specially coated recordable CD and DVD media to produce laser-etched labels with text or graphics, as opposed to stick-on labels and printable discs.
