We describe a birefringence measurement bench that allows fast two-dimensional measurements of low-birefringence fields in large transparent samples. We present calculations that show that, even when a birefringence bench exhibits defects (nonideal components, misalignments, etc.), measurements can be performed under realistic conditions without any <i>a priori</i> knowledge of the origin of the bench defects. This allows the measurement of birefringence fields on large-scale samples by use of an array of detectors instead of a single detector element, with a sensitivity of 3 × 10<sup>−4</sup> rad for 2-s data integration.
