VIC-3D-Micro-DIC系統(tǒng)可為小視場(chǎng)提供高分辨率的全場(chǎng)應(yīng)變、變形和疲勞測(cè)量及3D視頻引伸計(jì)測(cè)量。該系統(tǒng)是基于VICTM系列軟件(Vic-Snap，Vic-3D和Vic-Gauge)的解決方案，是3D-Micro-DIC硬件與Vic^TM軟件相結(jié)合的實(shí)用設(shè)備，可方便的在小尺度材料測(cè)試和結(jié)構(gòu)分析中快速可靠地運(yùn)行。

The VIC-3D-Micro-DIC system is used for full-field strain, deformation, and fatigue measurements on small field of view with high resolution (5Mpx) or as 3D Video-Extensometer (up to 500Hz). The measurement principle is digital image correlation based on the world wide established VICTM software (VicSnap, Vic-3D and Vic-Gauge). The  3D-Micro-DIC sensor hardware and Vic-software are fusing to a practical high end device for quick and reliable operation in material testing and structural analysis.
