Figure 1 - Schematic of the FPI data acquisition method. Angle of incidence of photometer = 45 degrees. Distance to specimen (with specimen in place) = 89 mm (3.5 in.). Angle of incidence of ultraviolet light = 60 degrees. Distance to specimen (with specimen in place) = 203 mm (8 in.). Angle of arm of ultraviolet light = 10 degrees. Angle of photometer with respect to ultraviolet light = 90 degrees. Ultraviolet light intensity = 1.54 lm ± 0.007.
