Abstract
In the first part of our paper, a method based on digital holographic interferometry and its application to measurements of the elastic properties of the bone is presented. Samples of bone were loaded and deformed and a large number of interferograms (digital holograms) were recorded over a short period of time. The phase of the wave front was calculated from the recorded holograms by using the two dimensional digital Fourier-transform method. Consecutive phase measurements allowed the calculation of deformation of wet objects during loading and fracture. The system allows the measurement of out and in-plane deformations simultaneously. In the second part of the paper, we present endoscopic systems, which are adapted for perfroming measurements of biological tissues in hidden cavities.
