Evaluating the elastic modulus of bone using electronic speckle pattern interferometry

ConclusionThe elastic modulus of bovine bone has been measured using a simple inverse approach, which incorporates experimental results obtained using electronic speckle pattern interferometry. The speckle fringe patterns were processed using a two-dimensional Fourier transform to obtain the phase related beam displacement. Assuming that the bone is an isotropic solid, the elastic modulus of the bone was found to be 19.8 ± 1.1 GPa. A calibration procedure suggests that the measurements are within 2% error.
