Thermal infrared near-field spectroscopy.
Despite the seminal contributions of Kirchhoff and Planck describing far-field thermal emission, fundamentally distinct spectral characteristics of the electromagnetic thermal near-field have been predicted. However, due to their evanescent nature their direct experimental characterization has remained elusive. Combining scattering scanning near-field optical microscopy with Fourier-transform s...
متن کاملNovel Application of Near-infrared Spectroscopy and Chemometrics Approach for Detection of Lime Juice Adulteration
The aim of this study is to investigate the novel application of a handheld near infra-red spectrophotometer coupled with classification methodologies as a screening approach in detection of adulterated lime juices. For this purpose, a miniaturized near infra-red spectrophotometer (Tellspec®) in the spectral range of 900–1700 nm was used. Three diffuse reflectance spectra of 31 pure...

متن کاملNondestructive Firmness Estimation of Tomato Fruit Using Near-Infrared Spectroscopy
Today, nondestructive methods are widely used to determine the quality of agricultural products. Meanwhile, visible and near-infrared (Vis/NIR) spectroscopy is regarded as one of the most widely used methods in the field of quality assessment of agricultural products. In this study, a system was developed to measure the Vis/NIR spectra of tomato fruit samples in the half-transmittance mode of m...
متن کاملbrain near-infrared spectroscopy (nirs)
near-infrared spectroscopy (nirs) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum. typical applications include medical and physiological diagnostics. nirs can be used for non-invasive assessment of brain function through the intact skull in human subjects by detecting changes in blood hemoglobin concentrations associated with neural activity, e.g., ...
