Vic-3D High Speed Imaging

The Vic-3D HS™ sys­tem allows for mea­sure­ment of very high speed events. As with all of our Vic-3D sys­tems, sur­face dis­place­ments and strains can be mea­sured in 3D. Vic-3D HS sys­tems instead include two ful­ly-inte­grat­ed high speed cameras.

 

High-Speed cam­eras are very use­ful for the qual­i­ta­tive assess­ment of high speed events, how­ev­er, it can be very tedious to obtain quan­ti­ta­tive data from images obtained this way. Mark­er track­ing soft­ware helps with this prob­lem, but can only track move­ment, and does so for a rel­a­tive­ly small num­ber of points. In addi­tion, it is nor­mal­ly not pos­si­ble to accu­rate­ly mea­sure move­ments toward or away from the camera.

Vic-3D HS pro­vides all the ben­e­fits of 3D Dig­i­tal Image Cor­re­la­tion in a sys­tem that includes ful­ly-inte­grat­ed high-speed cam­eras. Both move­ment and strain can be tracked for every pix­el with­in the field of view. And, since this data is cal­cu­lat­ed in 3 dimen­sions, it also includes any dis­place­ments direct­ly toward or away from the cam­eras. All cal­cu­la­tions are done quick­ly and auto­mat­i­cal­ly by the includ­ed software.

The Vic-3D System

Vic-3D is a pow­er­ful sys­tem for mea­sur­ing and visu­al­iz­ing of shape, dis­place­ment and strain, move­ments and vibra­tions of sur­faces in three dimen­sions. Vic-3D is a com­plete, turn-key sys­tem. It includes all nec­es­sary hard­ware and the most up-to-date soft­ware by Cor­re­lat­ed Solu­tions. Vic-3D is based on the prin­ci­ple of Dig­i­tal Image Cor­re­la­tion. Using this method, actu­al 3D object sur­face dis­pal­cement and strains (e. g.  the Lagrangian strain ten­so) is mea­sured and is avail­able at every point on the specimen’s surface.

Vic-3D can mea­sure arbi­trary dis­place­ments and strains from 50 micros­train to 2000% strain and above, for spec­i­men sizes rang­ing from <1mm to >100m. Set­up is sim­ple, requir­ing only a quick, flex­i­ble cal­i­bra­tion pro­ce­dure, and an applied ran­dom speck­le pat­tern. No spe­cial illu­mi­na­tion or lasers are required. And, no spec­i­men con­tact is required dur­ing testing.

System Features

Our sys­tems and analy­sis soft­ware are designed with the user in mind and are sim­ple to set-up, cal­i­brate and oper­ate. Some of the fea­tures of our sys­tems include:

  • Ver­sa­til­i­ty and Con­ve­nience: With our extreme­ly portable Vic sys­tems, data can be col­lect­ed in a wide range of set­tings with ease. Results can be processed on-the-spot, or data can be export­ed for analy­sis in the con­ve­nience of your office. And, pro­cess­ing can be done on any Win­dows PC with flex­i­ble float­ing licenses.
  • Soft­ware Inte­gra­tion and Ease of Use: The Vic soft­ware fam­i­ly is extreme­ly easy to use, and pro­vides a user inter­face con­sis­tent with all the oth­er appli­ca­tions you use. Our soft­ware includes pow­er­ful tools for visu­al­iza­tion. And, you can copy and paste all graphs and plots direct­ly into your favorite soft­ware to gen­er­ate reports.
  • Per­for­mance and Accu­ra­cy: The Vic image cor­re­la­tion algo­rithms are accu­rate and extreme­ly fast. In fact, real-time pro­cess­ing can be achieved using a mod­ern, con­sumer, quad-core proces­sor. This saves you valu­able time, and ensures reli­able results.
  • Expe­ri­ence, Knowl­edge, Tech­ni­cal Sup­port: The Cor­re­lat­ed Solu­tions engi­neer­ing team includes the peo­ple who invent­ed image cor­re­la­tion and writes the soft­ware. Isi-sys GmbH build the sys­tems and pro­vide all the tech­ni­cal sup­port. We have the expe­ri­ence to tack­le the most chal­leng­ing appli­ca­tions, and help you get the most out of your system.

The Vic-2D System

Vic-2D can mea­sure in-plane dis­place­ments and strains on pla­nar spec­i­mens. The set­up is sim­ple, for sam­ple prepa­ra­tion only the appli­ca­tion of a ran­dom speck­ly pat­tern is ness­esary. No spe­cial illu­mi­na­tion or lasers are required.
