The following table compares our measurement systems in terms of the measured variables.
Above all, Q400 and LIMtrack can calculate by the integrated scripting other measures (Young's-modulus, temperature coefficient of expansion, etc.).

1 Integral:
With the RTSS video extensometer, the strain is measured from the distance change of two markers. The measured value is the average (integral) component elongation between the markers.
With the Q400-DIC system, the integral (location-averaged) measured values (extensometer, polygon surfaces, circular surfaces, etc.) are calculated after the correlation.
