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 guidance is used by military to guide a missile or other projectile or vehicle to a target by means of a laser beam, either beam riding guidance or semi-active laser homing (SALH). [7] With this technique, a laser is kept pointed at the target and the laser radiation bounces off the target and is scattered in all directions (this is known ...
Schematic diagram of a typical laser, showing the three major parts. A laser is constructed from three principal parts: An energy source (usually referred to as the pump or pump source), A gain medium or laser medium, and; Two or more mirrors that form an optical resonator.
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 ...
Laser color television (laser TV), or laser color video display, is a type of television that utilizes two or more individually modulated optical (laser) rays of different colors to produce a combined spot that is scanned and projected across the image plane by a polygon-mirror system or less effectively by optoelectronic means to produce a color-television display.
The purpose of all lighting consoles, however is the same: to consolidate control of the lights into an organized, easy-to-use system, so that the lighting designer can concentrate on producing a good show. Most consoles accept MIDI Show Control signals and commands to allow show control systems to integrate their capabilities into more complex ...
The light from the projected image is not inherently polarized. New LED and laser DLP display systems more or less eliminate the need for lamp replacement. DLP offers affordable 3D projection display from a single unit and can be used with both active and passive 3D solutions. Lighter weight than LCD and plasma televisions.
