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.
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 ...
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.) [1] Dryer was disappointed because the resulting film, LaserImage, [2] did not have the pure color and shimmer of laser l
Time of flight of a light pulse reflecting off a target. A time-of-flight camera (ToF camera), also known as time-of-flight sensor (ToF sensor), is a range imaging camera system for measuring distances between the camera and the subject for each point of the image based on time-of-flight, the round trip time of an artificial light signal, as provided by a laser or an LED.
Ray optics explanation (focused laser). In addition to keeping the bead in the center of the laser, a focused laser also keeps the bead in a fixed axial position: The momentum change of the focused rays causes a force towards the laser focus, both when the bead is in front (left image) or behind (right image) the laser focus.
The laser light show at Grand Coulee Dam, which began in 1989, is one of the largest light shows in the U.S. The 37 minute show runs daily from Memorial Day through September 30. An addition of fireworks lights up the sky above the dam each Memorial Weekend Sunday and July 4. The Grand Coulee Dam premiered its first non-laser light show in 1957 ...
Motion Capture: A high-resolution uniquely identified active marker system with 3,600 × 3,600 resolution at 960 hertz providing real-time submillimeter positions. Motion capture: Motion-capture (sometimes referred as mo-cap or mocap, for short) is the process of recording the movement of objects or people.
