Estimating Cosmological Parameters From Supernovae
In order to understand the contribution of matter, radiation, and dark energy in the universe, cosmologists have developed a set of cosmological parameters: matter (Ωm), radiation (ΩR), dark energy (ΩΛ). ...
Dimensional Metrology and the Smart Factory
The manufacturing industry has come a long way from Ford’s car plants that spurred innovation in the U.S. The assembly line was a revolutionary tactic for efficiency, but modern manufacturing is much more ...
Neural Imaging with Visible Light: Advanced Implantable Sensor
Previously, we discussed a technique for producing high resolution maps of neural activity in the brain called Optical Recording of Intrinsic Signal, or ORIS. Conventional methods for performing ORIS ...
Temperature Maps of Exoplanets
Ten years ago, the idea of detecting planets outside of our solar system (a.k.a. an exoplanet) was nothing more than a far-fetched dream. However, in the last few years, powerful ground based and space ...
Neural Imaging with Visible Light: Implantable Optical Sensors
Previously, we discussed how visible light in combination with implantable optical sensors was used to map epileptic neural activity and localize focal seizures on the surface of the brain. Scientists at ...
Machine Learning Enables OCT Imaging of Optic Nerve Head
Medical imaging of the optic nerve head (ONH) is immensely important to study vision disorders like nearsightedness and glaucoma. Doctors traditionally use optical coherence tomography (OCT scans) to ...
Calvarial Fracture Imaging Using Raman Spectrometry
Scientists from the City University of Hong Kong’s Department of Physics revolutionized calvarial fracture imaging through the use of Raman spectroscopy. By allowing these defects to be imaged, the ...
Hidden in Plain Sight: Optical Cloaking
While most people would consider invisibility to be an unattainable superpower or limited to existing in sci-fi films, in reality, invisibility is not as impractical as it sounds. A technique, known as ...
Light Injection in Waveguide Connected Microdisks (WCM)
Researchers from the Harbin Institute of Technology at Shenzhen and Shanxi University have created a new configuration for waveguide connected microdisks (WCM). Their method could significantly reduce ...
Nanohole Fabrication Improves Anti-Reflective Properties
A team of researchers from the Korean Advanced Institute of Science and Technology has developed improved techniques for large-scale nanohole fabrication. Importantly, these nanoholes are used in ...
