“Normalized Difference Vegetation Index (NDVI) quantifies vegetation by measuring the difference between near-infrared (which vegetation strongly reflects) and red light (which vegetation absorbs).” How do you calculate NDVI? As shown below,Normalized Difference Vegetation Index (NDVI)uses the NIR a...
What is the difference between visible light and infrared radiation? What is a miniband quantum cascade laser? How does a metastable state act in laser media? How does fiber laser welding work? What is laser beam technology used for? What are three applications for laser technology? What wavel...
Light-induced infrared difference spectroscopy on three different forms of orange carotenoid protein: focus on carotenoid vibrationsOrange carotenoid protein (OCP) is a photoactive carotenoprotein involved in photoprotection of cyanobacteria, which uses a keto-catorenoid as a chromophore. When it absorbs...

Describe how a monochromator, a spectrograph, and a spectrophotometer differ from each other. Why is an Xe arc lamp used as an excitation source for fluorescence. What are its advantages? Describe the difference between infrared and Raman spectroscopy. Why are they considered complementary to each ...
It is demonstrated that in particular conditions a disordered medium composed of randomly distributed silicon nanoparticles exhibits a strongly negative scattering asymmetry in the near infrared due to multiple light scattering. As the concentration of scattering particles rises, the backscattering is also ...
Muscle oxygenation in the vastus lateralis (VL) was monitored using multi channel near-infrared spectroscopy. Half time reoxygenation (T(1/2)reoxy) after exercise was calculated from oxygenated hemoglobin in the eight channels which changed the distance between light source and detector distances at ...

Yes, humans naturally radiate heat and infrared energy. 9 What does it mean to irradiate food? Irradiating food involves exposing it to radiation to eliminate bacteria and extend shelf life. 8 How are irradiation and radiation different? Irradiation is the process of applying radiation, while radia...
