摘要
光学相干层析技术(OCT)是一种利用散射光相干原理进行成像的技术,具有无损、快速、高分辨率、断层成像等特点。物证鉴定要求尽量在不破坏物证原始状态下提取、检验、分析,获取有价值的信息,OCT作为一种光学检验技术能够满足该要求,其无需对样品进行预处理,就能实现相关物证的实时、原位、无损检验,在物证鉴定领域具有重要的应用价值。介绍了OCT的工作原理及其在物证鉴定领域中的应用。
Abstract
Optical coherence tomography (OCT) is a technique that uses the principle of scattered light coherence for imaging, with features of no destruction, fastness high resolution, and cross-sectional imaging. The identification of physical evidence requires as far as possible to extract, inspect, analyze and obtain valuable information without destroying its original state. As an optical inspection technology, OCT can meet these requirements. It can realize real-time, in-situ and non-destructive imaging without pre-processing the sample, which is of great significance in physical evidence identification. We introduce the working principle of OCT and its application in the field of physical evidence identification.
