Abstract
This paper proposes a new arrangement for an interferometric laserspeckle gauge. For the proposed setup
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 setup of the laserspeckle
strain gauge.
