    • Apparatus for measuring surface roughness utilizes diffraction patterns derived from the surface under test. The energies in the different orders are detected and processed utilizing various different algorithms dependent upon a number of factors such as the number of orders in the diffraction pattern and asymmetry in the diffraction pattern. Various filter functions both for the diffraction pattern itself and for values of surface roughness after measurement are disclosed. One algorithm for measuring surface roughness involves comparison of values representing the energy orders with reference values, preferably reference values obtained by an interpolation operation between one set of reference values representative of a diffraction pattern from a symmetrical surface and another set representative of a diffraction pattern from an asymmetrical surface.
    • 用于测量表面粗糙度的设备利用衍射自被测表面的衍射图。 使用各种不同的算法来检测和处理不同顺序的能量,这些算法取决于许多因素,例如衍射图中的阶数和衍射图中的不对称性。 公开了用于衍射图案本身和测量后的表面粗糙度值的各种滤光器功能。 用于测量表面粗糙度的一种算法涉及将表示能量阶数的值与参考值进行比较,优选通过表示来自对称​​表面的衍射图案的一组参考值与代表衍射图案的另一组之间的内插操作获得的参考值, 不对称的表面。
