摘要
It is shown that a turn of an object in holographic reversible shearing interferometry in the case of objects with linear dimensions not exceeding half the diameter of a probe light beam allows the doubling of the sensitivity of interferograms mapping changes in a wavefront caused by the object. The interference patterns of a glass test plate with the doubled sensitivity of inhomogeneity mapping obtained by this method are presented.
