Fig. 1From: Open software and standards in the realm of laser scanning technologyReflectance and absorption of light as a function of wavelength. (Top) reflectance of different materials – vertical red lines are at 532 nm and 1064 nm wavelengths of solid state lasers – seawater and ice have very low reflectance values thus overlap at this scale. Data are taken from the open ASTER spectral library [13]; (bottom) light absorption by water from various literature – open data collected from resources in Scott Prahl’s web page [14]Back to article page
