Portable Refrigerant Identification by Near Infrared Spectrophotometry

Design of a Near Infrared Spectrophotometry Brain Imaging System

Measuring brain activity is at task generally left for EEG or fMRI. However, there is a lesser known imaging technique known as near infrared spectrophotometry, in which near infrared light is shown into the patients head to measure changes in oxygenation that directly relate to brain activity. This paper describes a low-cost, wireless, portable near infrared spectrophotometry system that is ab...

Techniques to Identify Palatable Beef Carcasses: Marc Tenderness Classification, SDSU Colorimeter and Near-Infrared Spectrophotometry (NIR) Systems

Theoretical spectra of terrestrial exoplanet surfaces

We investigate spectra of airless rocky exoplanets with a theoretical framework that self-consistently treats reflection and thermal emission. We find that a silicate surface on an exoplanet is spectroscopically detectable via prominent Si–O features in the thermal emission bands of 7–13μm and 15–25μm. The variation of brightness temperature due to the silicate features can be up to 20 K for an...

Near-infrared spectrophotometry: a new dimension in clinical chemistry.

The near-infrared (NIR) spectral region (700-2500 nm) is a fertile source of chemical information in the form of overtone and combination bands of the fundamental infrared absorptions and low-energy electronic transitions. This region was initially perceived as being too complex for interpretation and consequently was poorly utilized. Advances in chemometric techniques that can extract massive ...
