The changes in [oxy-Hb] and [deoxy-Hb] were calculated from the difference in the light absorption characteristics of these chromophores according to the Beer–Lambert law.
Webb30 nov. 2024 · There are two general categories of NIR devices: filter-based and full-spectrum. Filter-based devices are particularly well suited to most types of processing, according to Bogart. NIR filter-based equipment blocks visible light and allows only certain wavelengths of IR light to enter the device. WebbHow does a NIR machine work? In NIR spectroscopy, the unknown substance is illuminated with a broad-spectrum (many wavelengths or frequencies) of near infrared light, which can be absorbed, transmitted, reflected or scattered by the sample of interest. The illumination is typically in the wavelength range of 0.8 to 2.5 microns (800 to 2500nm).
