Fiber-Optic Environmental Radiation Dosimeter
An all-optical, fiber-optic-coupled remote radiation sensor was developed using luminescent, copper-doped quartz material. The key to the technology is the doped quartz material, which produces a luminescence signal that is directly proportional to the radiation dose.
Briefs: Photonics/Optics
The scanning tunneling microscope (STM) has become one of the most powerful tools used in studying the surface structure of electrically conducting solid-state materials at an atomic...

Neuroimaging Technique May Help Predict Autism Among High-Risk Infants
According to a recent study, functional connectivity magnetic resonance imaging (fcMRI) may predict which high-risk, 6-month-old infants will develop autism spectrum disorder by age 2 years.
Articles: Photonics/Optics
As signal rates approach 50 Gb/s, bandwidth demand has outpaced conventional circuit boards. Engineers are now turning to PAM4 signaling rather than conventional NRZ as the most viable...
Briefs: Photonics/Optics
Optical lenses that can see features smaller than the wavelength of light cannot be made from conventional materials. Creating “hyperlenses” that can take ultra-sharp images needs both designer...
Briefs: Photonics/Optics
Researchers at Columbia University have made a significant step toward breaking the so-called “color barrier” of light microscopy for biological systems, allowing for much more...
