The trap-forming hologram also can specify the mode structure of each trap individually, thereby creating arrays of optical vortices, optical tweezers, and holographic line traps, for example. [55] When implemented with a spatial light modulator , such holographic optical traps also can move objects in three dimensions. [ 56 ]
Laser power used for trapping the cell is 100 mW, for stretching 1200 mW per fibre. Phase contrast images, 63× objective; scale bar is 10 μm. The trapping of micrometre-sized particles by two laser beams was first demonstrated by Arthur Ashkin in 1970, [1] before he developed the single-beam trap now known as optical tweezers. An advantage of ...
A laser projector is a device that projects changing laser beams on a screen to create a moving image for entertainment or professional use. [1] It consists of a housing that contains lasers, mirrors , galvanometer scanners, and other optical components.
BERLIN, Sept. 04, 2024 (GLOBE NEWSWIRE) -- JMGO, a pioneer in optical technology, will showcase its in-house developed MALC™ (Microstructure Adaptive Laser Control) 2.0 Triple Laser Optics at IFA 2024 in Berlin. This innovation is set to redefine laser projection by overcoming the industry’s persistent challenge of achieving high brightness ...
The Laser Clay Shooting System (レーザークレー射撃システム) is a light gun shooting simulation game created by Nintendo in 1973. The game consisted of an overhead projector which displayed moving targets behind a background; players would fire at the targets with a rifle, in which a mechanism of reflections would determine whether or not the "laser shot" from the rifle hit the target.

A speaker giving a presentation with an RF pointer in his left hand. Using a wireless clicker, helps the presenter to move freely, instead of being obliged to stay next to the computer, can get closer and keep in touch with the audience, watching the presentation together with them, being able to use the built-in laser pointer, in order to emphasize specific points in the dialogue with the ...
