尽管石器使用磨损分析是一种广为接受的研究工具，但其定性性质仍然受到损害。已经努力量化使用磨损分析，但成功有限。本文将提出一种新的分析方法的基础上的非破坏性测量技术，激光轮廓术。这种光学技术，与适当的软件相结合时，允许在几个长度尺度的粗糙度参数的容易测量。这说明了表面形貌的长度尺度依赖性，并允许其定量描述。此外，在某些情况下，来自这种类型的测量的信息可以通过分形几何来描述，从而产生新的解释可能性。初步结果表明，可以对几种不同的燧石和黑曜石样品进行测量，并根据它们的磨损历史进行区分。
Lithic use-wear analysis, despite being a well-accepted research tool, is still undermined by its qualitative nature. An effort has been made to quantify use-wear analysis, but only with limited success. This paper will present a new method of analysis based on a non-destructive measurement technique, laser profilometry. This optical technique, when coupled with appropriate software, allows for easy measurement of roughness parameters at several length scales. This accounts for the length-scale dependence of surface topography and allows for its quantitative description. Further, the information from this type of measurement can, in some cases, be described by fractal geometry leading to new interpretive possibilities. Initial results showed that measurements could be made on several different chert and obsidian samples and that these could be distinguished based on their wear histories.
