The geometry of the measurements in: (a)
transmittance mode, (b) reflectance mode: (1) the incident beam (diameter 3 mm) (2) the bone sample (3)
the entrance port (square mm) (4) the transmitted (or diffuse
reflected) radiation (5) the integrating sphere (inner diameter is 100 mm) and (6) the exit
port (diameter 16 mm).
