Evaluating the Elastic Modulus of Bone Using Electronic Speckle Pattern Interferometry

Validating a voxel-based finite element model of a human mandible using digital speckle pattern interferometry

“…To date, few studies have applied DSPI to bone, either for measuring strains (Kessler et al, 2006;Su et al, 2005;Tyrer et al, 1995; or elastic properties of loaded bones (Barak et al, 2009;Shahar et al, 2007;Zaslansky et al, 2005;Zhang et al, 2001). The results of these studies confirm the high reliability and practicality of this technique compared to strain gauges.…”

Applications of digital image correlation to biological tissues

“…Some noteworthy examples include the use of holographic interferometry to identify soft tissue abnormalities, 1 to evaluate structural changes posed by the placement of orthopedic devices, 2,3 and to enhance the efficacy of medical and dental practices. 4 -6 Geometric Moiré, Moiré interferometry, and electronic speckle pattern interferometry ͑ESPI͒ have also been used to study the properties of hard tissues such as bone 7,8 and the dentin and enamel of teeth. [9][10][11] Laser-based optical methods for displacement measurement are very precise and typically capable of resolving submicrometer displacements.…”

Biological Systems and Materials: A Review of the Field of Biomechanics and the Role of the Society for Experimental Mechanics

“…Mechanical testing techniques have been published to address the measurement of constitutive behavior, [15][16][17][18] fracture and fatigue, 19 dynamics, 20,21 and wear. 22 An array of optical techniques has been developed based on interferometry, [23][24][25][26] digital image correlation, [27][28][29] and photoelasticity 30 to measure biological materials and structures. Moreover, the classic techniques of the society have been adapted to biomechanics with strain gages 31,32 and modal analysis.…”
