The near-infrared (NIR) window (also known as optical window or therapeutic window) defines the range of wavelengths from 650 to 1350 nanometre (nm) where light has its maximum depth of penetration in tissue. Within the NIR window, scattering is the most dominant light-tissue interaction, and … See more The absorption coefficient ($${\displaystyle \mu _{a}}$$) is defined as the probability of photon absorption in tissue per unit path length. Different tissue components have different $${\displaystyle \mu _{a}}$$ values. Moreover, See more Optical scattering occurs due to mismatches in refractive index of the different tissue components, ranging from cell membranes to … See more • Optical window • Near-infrared spectroscopy See more The NIR window can be computed based on the absorption coefficient spectrum or the effective attenuation coefficient spectrum. A possible criterion for selecting the NIR window is given by the FWHM of the inverse of these spectra as shown in Figure 7. See more WebDec 20, 2024 · window, are versatile in applications such as anti-counterfeiting, time-domain manipulation, and biological thermal probes.
