Final answer:

To analyze carpet fibers at a crime scene non-destructively, forensic scientists may use microscopical analysis or infrared spectroscopy, which allows examination of the fiber's structure and chemical composition without destroying the evidence.

Step-by-step explanation:

The non-destructive technique used for analyzing carpet fibers at a crime scene is likely to be microscopical analysis or a spectroscopic method such as infrared spectroscopy. While RFLP analysis is used for DNA fingerprinting in forensic science, analyzing fibers requires techniques that can preserve the evidence for further tests. Techniques such as high-powered microscopy allow for the examination of the physical characteristics of fibers, including their structure and any trace materials adhered to them without destroying the sample. When detailed chemical composition is required, methods like infrared spectroscopy can be used to determine the molecular makeup of the fibers, which helps in tracing their origin or comparing them with known samples. These methods are instrumental for forensic scientists in criminal investigations.
