Abstract
It is suggested that holographic interference patterns recorded in oppositely directed beams as proposed by Yu. N. Denisyuk be used to study static problems in the mechanics of deformed samples. The photographic plates are attached to the surface of the sample on top of an intermediate optically transparent material. The effects of the rigidity of the photographic plate and optically transparent material on the measured deformations and the vibrational noise reaching the photographic plate are estimated. Equations are derived which relate the displacements of points on the deformed sample surface to the difference in path lengths of the interfering waves. The method is illustrated by considering the deformed state of a spherically stressed sample using a slit condenser.
