Imaging tools help us see into the world that is not possible with our naked eyes. It was with the invention of the microscope and the telescope that big frontiers in science were reached. We unlocked the ...

Non-linear techniques in photonics have opened up new avenues for sensing and manipulating materials. In the 1960s, non-linear techniques were used to discover multiphoton absorption processes in ...

X-Rays and Imaging We commonly associate x-ray imaging with hospitals and broken bones, but why are x-rays the chosen source of radiation instead of visible light or electron beams? The high initial energy ...

A research team from the Military Technical College and from Cairo University in Cairo, Egypt have developed a fluorescence hyper-spectral imaging system which can be employed for diagnosis and detection ...

  Developing a clear characterization of a tumor’s microenvironment is imperative in understanding its progress. A new approach to determining cancer’s development involves a thorough study of ...

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 ...

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 ...

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 ...

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 ...

A joint team of researchers from the Korea Advanced Institute of Science and Technology and the Seoul National University have achieved in vivo imaging of the endothelial surface layer. The endothelial ...
