3D-Micro-DIC System

The 3D-Micro-DIC ste­reo sen­sor sys­tem is deve­lo­ped for full field strain and defor­ma­ti­on mea­su­re­ment on small FOV with hig­hest pre­cisi­on and reso­lu­ti­on over the com­ple­te field of view by 3D digi­tal image cor­re­la­ti­on (DIC). It also ope­ra­tes as exten­so­me­ter for real-time stain con­trol. The Examp­le below shows the new sen­sor ver­si­on 2019 for 1:1 magni­fi­ca­ti­on. FOV ran­ge starts from 2:1 with 4.2 x 3.5 mm @ 5Mpx and 75Hz.

Advantages and features of  the 3D-Micro-DIC system:

  • Com­pact and rigid design, quick set-up and easy handling
  • Pre-adjus­ted, fixed field of view and sta­ble calibration
  • Spe­cial­ly desi­gned for small and very small field of view (FOV)
  • Reli­able and fast USB 3.0 inter­face for Desk­top or Lap­top PCs
  • Turn-key solu­ti­on inclu­ding Vic-Snap and Vic-Gau­ge 3
  • DRo­bust and reli­able post-pro­ces­sing with Vic-3D

Technical highlights of the 3D-Micro-DIC system

  • 3D full field (5Mpx@75Hz frame rate) con­ti­nuous­ly record­ing on SSD
  • Hig­her frame­ra­tes at redu­ced resolution
    (e. g. [Pixel@Hz]: 1600x1200@133; 1920x1080@148; 1280x720@217; 800x600@258; 640x480@315; 320x240@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
