Abstract
This technical note presents a technique for estabalshing the boundary retardation with respect to the observed finges. Thus, the available data are increased and, thereby, improve the accuracy of determining fringe spacing near boundaries and, in particular, in thin models. The technique is applicable to scattered-light polariscopes utilizing a quarter-wave plate to circularize the entering polarized light.
