Original Kurzfassung:
This paper proposes a new arrangement for an interferometric laser–speckle gauge. For the proposed set–up
geometrical inaccuracies are assumed. Therefore, we are looking for a sensor position, where the geometrical
inaccuracies are having the smallest impact on the measurement result. For the measurement of an applied
measurand vector to the observed specimen, we suggest a linear unbiased minimum variance estimator. Theory
an measurement results using this estimator are shown for a specific measurement set–up of the laser–speckle
strain gauge.
