运用三维激光共聚焦显微镜OLS4000对复合轧辊的组织进行观察, 并与传统光学显微镜莱卡DM IRM所采集到的图像相比较。结果表明: 三维激光共聚焦显微镜是超大景深显微镜, 清晰度较高, 弥补了传统显微镜观察2 000倍以上图像时聚焦不实的缺点, 并且它具有独特的图像自动拼接功能, 可对大面积试样进行全貌分析, 使图像连贯性更好, 在观察轧辊组织二维图像的同时还可以获得该组织的三维立体图像。在使用过程中与其他的金相技术相配合, 可以作为一种先进的技术手段对复合轧辊的深层组织形貌进行直观的科学观察与分析。

The microstructure of composite rolls was studied by 3D measuring laser microscope OLS4000, and compared the image with traditional microscope DM IRM. The results showed that the OLS4000 has been used to assess and measure a wide variety of material surfaces and artifacts from the nano up to the macro scale. The OLS4000 is a confocal laser scanning microscope which has helped in the assessment of material surfaces, as it provides 3D images and has measurement capability. It with greater accuracy than an optical microscope. Measurements made using the OLS4000 are easier and produce a more accurate value due to the high lateral resolution of the microscope. Together with other metallographic technology in using process, it can be used as an advanced technology of scientific observation and analysis for the depth tissue morphology of composite rolls.
