Abstract:

Measurements were made of the reflectivities of some typical laser rangefinder target materials by two methods and at two wavelengths. The first method involved the measurement of the return signal strength in laser rangefinders operating on targets in the field with allowance for the geometry of the target. The second method employed a spectrophotometer in the laboratory to find the diffuse reflectivity of material samples. Some interpretation of the results is given, including especially the differences due to the wavelengths used.
