Abstract

A particular optical configuration has been used by the authors to holographically obtain interference patterns which are unsensitive to rigid body translations. The fringe pattern depends on the strains and any rotations of the body. When a curved surface or several flat surfaces of a homogeneous body are viewed simultaneously, rotations can be eliminated from the fringe pattern, and the strain in the viewing direction can be determined from a single view of the hologram. This technique has been used to measure the thermal expansion coefficients of a beryllium rod and the shear modulus of an aluminum bar with an accuracy of a few percent.
