VIC-Strainograph 3D 小尺度测量DIC系统

 

VIC-Strainograph-3D相机系统(SG-3D)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VICTM系列软件(Vic-Snap,Vic-3D和Vic-Gauge)的解决方案,是Strainograph-3D相机硬件与VicTM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 Strainograph-3D camera (SG-3D) 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  Strainograph-3D 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 Strainograph SG-3D

  • 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
