Quality of laser beam shaping can be enhanced at no extra cost

Researchers from Osaka University have developed a technique for improving accuracy of laser beam shaping and wavefront obtained by conventional methods with no additional cost by optimizing virtual phase grating. The results ...

Researchers create fiber optic sensors that dissolve in the body

For the first time, researchers have fabricated sensing elements known as fiber Bragg gratings inside optical fibers designed to dissolve completely inside the body. The bioresorbable fiber Bragg gratings could be used for ...

Laboratory breakthrough may lead to improved X-ray spectrometers

Researchers at the Paul Scherrer Institute's Swiss Light Source in Villigen, Switzerland, have developed a new design for X-ray spectrometers that eschews a commonly utilized component to lowers overall production costs and ...

The molecular breakdance of seeing

The detection of light by pigments in the retina, called rhodopsin or visual purple, leads to our sense of vision. New experiments by scientists from the Max Planck Institute for the Structure and Dynamics of Matter and the ...

The science and engineering behind Amsterdam's "Rainbow Station"

If you're passing through the Amsterdam Central train station you may be pleasantly surprised to see a vibrant rainbow projected on the large arch that spans over its platforms. It's the "Rainbow Station" project by artist ...

Exploring X-ray phase tomography with synchrotron radiation

X-ray phase tomography is an imaging technique that uses penetrating X-rays to create volumetric views through "slices" or sections of soft biological tissues, such as tumors, and it offers strongly enhanced contrast compared ...
