Toward extremely efficient, lensless, holographic laser projectors
A new projection method using laser diodes, optical fibers, and liquid crystal phase modulators can produce color, high-quality, high-contrast images with a handheld device and without photon loss.
Plasmonic optical tweezers can form characteristic micropatterns
Light irradiation of a metallic nanostructure enables a novel thermoplasmonic optical tweezer for nanoparticles.
Multimedia presentations: Plenary talks from SPIE Advanced Lithography 2013
SPIE Advanced Lithography 2013 featured plenary presentations from leaders in the lithography industry.
Newer optics efficiently mix, dim, and color-tune LED lightStories 11 - 20 of 306
Low-cost, plastic-injected optics mix light from different color LED dies without a significant decrease in average brightness, simplifying luminaire design both optically and electronically.
