应用总结003：全字符油墨的简化成像

　　概述

　　Whole character ink analysis can reveal previously unknown information such as doctored characters and pen contact on the paper using the Renishaw StreamLine™ fast imaging technique. This was not previously practical using Raman microscopy due to the required long exposure times and laser damage. StreamLine imaging can provide unique information based on chemical differences between the inks and paper. This is important in the analysis of questioned documents.
