Camera Technology

At Dantec Dynamics, we embrace, integrate, and support the very latest in what camera technology has to offer so you can do more with Digital Image Correlation (DIC). Istra4D is one of the only commercially available DIC software platforms that support; CoaXPress-12, 10GigE, USB3, and GigE giving users the flexibility to choose the best camera technology for any given materials testing application.

To support a wide range of material testing applications, Dantec Dynamics offers a large camera technology portfolio. For testing applications that require;

  • higher resolution cameras to capture small, detailed and localized strains, we offer camera models from small (<3 Mpx) to ultra-high (>13 Mpx) resolutions.
  • medium speed cameras to capture quick, transient events (e.g. peak or valley triggering during a fatigue test), we offer camera models from low (<100 Hz/fps) to ultra-high (>4000 Hz/fps) frame rates.
  • cameras with longer cable lengths to perform measurements in safety-critical and access-limited areas, we offer camera models with short (<10 m) to extra-long (>70 m) cable lengths.
  • multicamera solutions to measure; samples & coupons in sizes from millimeters (mm2) to structures of multiple meters (m2), we offer camera models with 4-camera to 16-camera multicamera capability.

Cameras that save/transfer data directly to a PC are known as “continuous-mode” cameras. The performance of continuous-mode cameras is described through the bandwidth of the corresponding transport layer (i.e. Low-Speed & Medium-Speed cameras), which describes how much data (Megabits/Gigabits) the technology can continuously transfer (and be managed) by the PC, per second (Megabits per Second/ Gigabits per Second). In Figure 3 above, the respective camera technology bandwidth (line) can be seen for the individual cameras offered.

Each camera technology has different performance attributes, which are dependent on the bandwidth & technology of the corresponding interface/transport layer;

  • Resolution is a characteristic that describes the number of pixels (px) within an imaging chip
  • Acquisition Speed: also known as frame rate (fr) is the speed of the camera, specifically the speed at which one frame can be captured continuously listed as frequency (Hz) or frames per second (fps).
  • Multi-Camera Setup Capability: refers to the number of cameras that can be used at one time (in sync) during a measurement series acquisition
  • Cable Length: refers to the length of the data & power cable/s connection between the camera/s and PC.
