Dresden Researchers Choose Kirana

Specialised Imaging is delighted to announce that the KIRANA has been chosen as the preferred Ultra High Speed video camera following a head-to-head comparison against alternative specification cameras.

The basis of the decision is detailed in a paper which compares images from the KIRANA with those taken by two alternative cameras for Digital Image Correlation (DiC) measurement analysis.

The paper, written by researchers at Dresden University was driven by research investigating the behaviour of concrete when subjected to high impact loading. To achieve accurate measurements, using Digital Image Correlation, the researchers evaluated the KIRANA from Specialised Imaging, The HPV-X2 from Shimadzu and the TMX 7510 from Vision Research (AMETEK). In addition, images were taken of two example impact events to compare real-world image quality and the effect on subsequent analysis results using ARAMIS Digital Image Correlation software from GoM/Zeiss. In conclusion the experimental tests and Correlation analysis results showed technology limitations that affected image quality could be mitigated to a level where significantly higher spatial resolution images provided better results overall.

We are also pleased to announce the researchers at Dresden are now continuing their study of concrete shock loading using their own KIRANA camera.
