数字图像相关技术(DIC)的测量依赖于制备在试件表面的随机的高对比度散斑,以获取最准确的测量结果。在实践中,如果散斑太稀疏、太密集、或者散斑点过大,都将使测量的空间分辨率受损。相反,如果散斑点太小、混叠,则可能会导致数据嘈杂。为了减少测量噪音和降低不确定度,需要制备符合视场(FOV)尺度和相机分辨率的理想散斑图案。VIC散斑制备套件的作用即是帮助用户能够轻松将理想散斑制备于试件表面,而无需对试件区域有精确的了解。该套件易用、灵活,适用于各种VIC-2DVIC-3D系统的应用场景。 该套件实际上消除了由于试件制备不当而导致的潜在测量偏差。

Digital Image Correlation (DIC) relies on a high-contrast random pattern applied to the specimen’s surface to produce the most accurate results. In practice, if the pattern is too sparse, too dense, or the speckles are too large, spatial resolution of the measurement will suffer. Conversely, if the speckles are too small, aliasing may result causing noisy data. To reduce noise and lower uncertainty, the ideal speckle pattern for the desired field of view (FOV) and camera resolution must be applied.  The VIC Speckle Pattern Application Kit enables the user to easily apply the ideal pattern to the surface of the specimen without any precise knowledge of sample area.  The kit is easy-to-use, flexible, and available for a wide range of applications suitable with your VIC-2D or VIC-3D system.  The kit virtually eliminates the potential bias that would result from poor sample preparation.

CSI公司提供的散斑制备套件包含一系列工具,以供新老DIC用户使用,来快速创建理想的散斑图案。针对不同视场和图像采集器分辨率组合,还提供散斑点尺寸建议表。 以下列出了套件中所包含的物品。

The speckle application kit from Correlated Solutions provides an array of tools which can be used by new and experienced DIC users alike to quickly create the ideal speckle pattern. Speckle size suggestion tables for multiple fields-of-view and sensor resolution combinations are also provided. The items included in the kit are shown and listed below.
