abstract：:The scattering phase functions for HeNe-laser light of dentine sections 10-20 micron(s) thick were measured. The functions perpendicular to the tubules had first-order maxima at angles of 4 degrees for bovine dentine and 5 degrees for human dentine; those parallel to the tubules showed no first-order maxima. Several c...
