Abstract

We propose a method for the precision measurement of interior displacement of three-dimensional transparent bodies by using speckle pattern technique. In this paper, we apply this method to displacement measurements in the interior of the human crystalline lens. The human crystalline lens (in vitro) is illuminated with a thin sheet-like beam of a laser light, and the speckle patterns created by the light scattering from the particles in the illuminating plane is recorded by double exposure with before and after deformation. In-plane displacement fringe patterns are obtained by optical spatial filtering techniques. This method is briefly discussed theoretically and the experimental results are presented to demonstrate the validity of this method.
