朱墨时序显微检验的技术要点及应用

Microscopic Examination of the Sequences of Crossed Stroke and Stamp Impression

朱墨时序鉴定常见的检验方法包括显微检验法、减层法及光谱法等,其中最基础也是最被普遍使用的方法是显微检验法。通过对显微镜检验在朱墨时序鉴定中的技术要点进行讨论,阐述如何通过选择不同的显微镜,调整放大倍率、照明方式、观察方式及运用共聚焦等技术手段达到最佳观察效果和检验图片。总结了朱墨时序显微镜检验所依据的表观特征及其观察和分析要点,希望对朱墨时序鉴定实践起到积极的指导作用。

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.
