VIC-3D-Micro-DIC 小尺度测量DIC系统
VIC-3D-Micro-DIC系统可为小视场提供高分辨率的全场应变、变形和疲劳测量及3D视频引伸计测量。该系统是基于VIC系列软件(Vic-Snap,Vic-3D和Vic-Gauge)的解决方案,是3D-Micro-DIC硬件与Vic软件相结合的实用高端设备,可方便的在小尺度材料测试和结构分析中快速可靠地运行。
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 VIC 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.

技术亮点 Technical highlights of 3D-Micro-DIC
-
3D全场图像(5Mpx @ 75Hz帧频)可连续记录在固态存储SSD上,单次实验可记录容量为SSD存储余量
-
通过降低图像传感器分辨率可获得更高帧率(例如[Pixel @ Hz]:1600×1200 @ 133; 1920×1080 @ 148; 1280×720 @ 217; 800×600 @ 258; 640×480 @ 315; 320×240 @ 576)
-
对应视频引伸计功能和实时反馈控制
-
应变噪声水平±0,001%(±10με),可通过时间平均获得更好噪声水平
-
根据FOV范围,变形灵敏度可达纳米尺度(1/100像素)
- 3D full field (5Mpx@75Hz frame rate) continuously recording on SSD
-
Higher framerates at reduced resolution
(e. g. [Pixel@Hz]: 1600×1200@133; 1920×1080@148; 1280×720@217; 800×600@258; 640×480@315; 320×240@576). - suitable for Video-Extensometer functions and real time feedback control
- Strain noise level of ±0,001% (±10µstrain) and better by time averaging
- Deformation sensitivity in nm range (1/100 pixel) depending on FOV
