"We aim to apply our spectrometer to microscopy, enabling the capture of 2D or 3D images with Raman scattering spectra.

By vertical, oil & gas is projected to hold largest market share in distributed fiber optic sensor market by 2030.

The surfaces that cells come into contact with can influence how the cells grow, function, and communicate—shaping metabolism ...

Science X is a network of high quality websites with most complete and comprehensive daily coverage of the full sweep of ...

Raman and Brillouin scattering are inelastic scattering processes in which the wavelength of the scattered radiation is different from that of the incident light and a change in the internal energy of ...

In contrast, a small amount of light is scattered at different wavelengths depending on the chemical structure of the analyte (Raman scattering). A Raman spectrum is a vibrational spectrum, where each ...

The schematic diagram [Figure (b)] shows that the Stokes beam is modulated with an electro-optic modulator (EOM, M350-160 KD*P, Conoptics) at a couple of MHz by using a square-wave function-generator ...

Scientists are now able to image a range of materials down to a sub-molecular level, thanks to light-based techniques based on Raman scattering developed by a team led by Jian-Guo Hou.

Frequency shifts are thus measured based on the amounts of energy involved in the transition between the initial and final stages of the scattering molecule. The Raman effect clarifies the ...
