Biological Application Example

bio_1A rat tibialis anterior muscle was under study in order to characterize its movements during electrical stimulation. This research was limited by conventional methods, where it was only possible to characterize the displacement of a small number of discrete points within the specimen. This analysis was complicated by the “bunching” which took place during muscular contraction. With such a limited number of data points, any strain calculations represented only gross averages over relatively large areas. Moreover, it was not possible to calculate displacements in three dimensions.

bio_2Using the Correlated Solutions VIC-3D measurement system, researchers were able to overcome these problems and obtain three-dimensional surface displacements on the same specimen. Small, local variations in these displacements were clearly resolved, as well as the corresponding strains (see figure on the left). Measurements were made rapidly and without need for contact with the specimen by the measurement system. And, all calculations were performed quickly and automatically by the measurement system. Thus, in addition to significantly improving the quality of available data, the VIC-3D system was able to save valuable time for researchers.
