How long does it take to acquire and analyze data for a measurement?
With full-field techniques, data for the entire sample is captured in each video frame, so data acquisition is independent of sample size. For DIC, data acquisition times are much less than 1 second. For fringe projection and shadow moiré, multiple image capture requires 1-2 seconds. Analysis typically takes a few seconds more. For example, minimum time between measurements during a temperature profile is set at 5 seconds.
