By developing a fast algorithm to map out the paths light takes through yogurt, researchers aim to someday see through skin.
Light Lasers and Optics
Seeing through materials
Graphene ‘phototransistor’ for imaging, communications
New light-detecting device senses light that doesn’t hit the graphene itself.
Twisted semiconductors for future moving holograms
Holographic displays need twisted light. Twisted semiconductors assembled with the help of amino acids may enable them.
Ultrashort light pulses for fast “lightwave” computers
Extremely short, configurable “femtosecond” pulses of light demonstrated by an international team could lead to future computers that run up to 100,000 times faster than today’s electronics.
Lasers can detect weapons-grade uranium from afar
Researchers have shown that a technique often used to identify chemicals at a distance could help sniff out illicit nuclear activities from as far as a couple miles away.
