Review of shortwave infrared imaging and spectroscopy in tissue [Invited].

ABSTRACT: The shortwave infrared (SWIR) wavelength band (1,000-2,000 nm) has recently garnered increased interest due to its beneficial attributes for tissue imaging and spectroscopy. Lower scattering, increased sensitivity to endogenous water and lipid content, and the reduced influence of melanin offer new measurement opportunities and application areas. SWIR sensor technology is advancing at a rapid pace, fueling growth in academic and commercial instrument development. Here, we review recent progress in SWIR tissue imaging and spectroscopy, provide resources on tissue optical properties at SWIR wavelengths, and offer guidance on the utilization of models, methods, and instruments for SWIR measurements in tissue. One key finding is that while some efforts have exploited the lower scattering in th
