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

*Integral:
The RTSS video extensometer measures the strain from the distance change of two markers. The measured strain value is therefore the average (integral) component elongation between the markers and similar to a mechanical extensometers
With the Q400-DIC system, the integral (locally averaged ) measurement values (extensometer, polygon surfaces, circular surfaces, etc.) are optionally calculated after the spatially resolved analysis.
