Microscopic Examination of the Sequences of Crossed Stroke and Stamp Impression

Common methods for the examination of the sequences of crossed strokes and stamp impressions include microscopic examination, layer-scraping, spectral testing and so on. But the most basic and most widely used method is the microscopic examination. This paper focuses on the techniques of microscopic method of examining crossed sequences, explains how to se- lect different microscopes, adjust magnification, illumination, observation modes, and use confocal and other technical meth- ods to achieve the best results and images. It also summarizes the apparent characteristics of different sequences with different materials, and corresponding key points of observation and analysis, aiming at providing guidance for the practice of examining sequences of crossed strokes and stamp impressions.
