Abstract

Active mid-infrared laser reflectance characteristics of 18 different bench-mark soil samples were measured at various angles of incidence between 0° and 80° at 9.283-, 9.569-,10.247-, and 10.633- μm wavelengths for both copolarized and cross-polarized conditions. Calibration was performed for each measurement using a Labsphere Intragold diffuse reflectance standard of 94% reflectance. One hundred independent reflectivity measurements were averaged for each combination to yield a mean reflectance value. The soil samples were characterized in terms of the soil taxonomy, mineralogy, geographic location, soil texture, and organic carbon content. Selected samples represented wide variability in soil properties. -from Authors
