Over the past 40 years, microelectronics have advanced by leaps and bounds thanks to silicon and complementary metal-oxide semiconductor (CMOS) technology, enabling computing, smartphones, compact and low-cost digital cameras, as well as most of the electronic gadgets we rely on...

A research team led by Professor YongKeun Park of the Physics Department at KAIST has developed an optical manipulation technique that can freely control the position, orientation, and shape of microscopic samples having complex shapes. The study has been published...

U.S. researchers have proposed an approach using another up-and-coming technique, photoacoustic microscopy (PAM), that could help cancer surgeons assess tumor tissue in the operating room rather than the biopsy lab, and thereby avoid the need for repeat surgeries to get...

Scientists from two Swiss institutions have used subwavelength resonant waveguide gratings (RWGs) to create a single-layer, thin-film beam-steering device that can color-filter and redirect a low-coherence white light source, such as light from a smartphone camera’s flash. The RWG-based design,...

An international team of researchers from the University of California, Los Angeles and the Braunschweig University of Technology in Germany has developed an approach to enhance the sensitivity of smartphone-based fluorescence microscopes by ten-fold compared to previously reported mobile phone-based...

An international team of researchers from Moscow State University (Russia), Sandia National Laboratories (U.S.), and Friedrich-Schiller University (Germany) have devised an ultrafast tunable metamaterial based on gallium arsenide nanoparticles. Their study was published in Nature Communications. The new optical metamaterial...

In recent years, a host of Hollywood blockbusters – including The Fast and the Furious 7, Jurassic World, and The Wolf of Wall Street – have included aerial tracking shots provided by drone helicopters outfitted with cameras. Those shots required...

The possibility of sending and receiving holographic messages has long tantalized sci-fi fans. Although we’re not there yet, scientists have now created holograms that can change from one image to another as the materials used to generate them are stretched....

Researchers at the University of California, Irvine are testing a new imaging device for its ability to monitor, quantify – and hopefully one day predict – skin toxicity levels induced by radiation therapy. Read more...

According to researchers, a video camera has been developed that can film at a rate equivalent to five trillion images per second, recording events as short as 0.2 trillionths of a second. The ultrafast camera, which enables 2D videography of...
