Abstract [en]

The system described uses a digital image correlation technique called Digital speckle photography (DSP) for the measurement of 3-D surface deformations. A stereoscopic technique with two perpendicular video cameras was developed to enable accurate measurements on arbitrarily shaped objects. Using the calibration algorithm described the main source of error are random errors originating from the correlation algorithm. Standard deviations of displacements as low as 2 micrometer for in-plane displacements and 12 micrometer for the out-of-plane component are reported, for an inspected area of 100 X 100 mm2.
