A method for tooth surface lustre measurements with a scanning reflectance sensor system is described. A fiber optic light beam of high intensity is projected onto the labial tooth surface. The reflected light at position X is conducted through the same fiber optic to a photodiode, amplified and recorded on an X-Y recorder. Position X is measured by a potentiometer in the rotation center of a rod to which the fiber optic head is attached and which can be moved parallel to the arcade of anterior teeth to be measured. The experimental system allows the assessment of differences in light reflection caused by light scattering resulting from roughened enamel surfaces and by stains.
描述了一种使用扫描反射传感器系统测量牙齿表面光泽度的方法。高强度的光纤光束投射到牙齿唇面。在位置X处的反射光通过同一根光纤传导至光电二极管，进行放大并记录在X - Y记录仪上。位置X由一个电位计测量，该电位计位于连接光纤头的杆的旋转中心，杆可平行于被测前牙牙弓移动。该实验系统能够评估由牙釉质表面粗糙导致的光散射以及污渍所引起的光反射差异。
