Describe the process of comparing two fibers via microscopic and analytical methods. What morphological characteristics should a criminalist compare in these steps?

What will be an ideal response?


Answer should include points such as the following:
A criminalist first microscopically compares the color and diameter of the fibers. Other morphological features that may aid in the comparison are lengthwise striations (i.e., lined markings) on the surface of some fibers and the pitting of the fiber's surface with delustering particles added in the manufacturing process to reduce shine. The cross-sectional shape of a fiber may also help characterize the fiber. Confirmation of a color comparison can then be made by comparing the fibers' spectral patterns with a microspectrophotometer. A physical characteristic that frequently is used to identify fibers is the infrared absorption spectrum.
