Abstract
The measurement and testing of 3D profile plays a vital role in characterizing orthopaedic bone plates. As being implanted in human body, its shape must be accurately defined in order to avoid harmful side effects. In present communication, we report a low-cost, non-destructive measurement of 3D surface profile of titanium bone plate using fringe projection and automated interferogram analysis technique. Collimated light from a He-Ne laser is incident on a grating and the resultant sinusoidal pattern is projected on bone plate sample. Resulting deformed fringe pattern carries the information of the sample surface. For measurement of 3D topographic information, interferograms are recorded and analyzed using Fourier transform method. The proposed setup provides its feasibility of being non-contact, non-destructive, fast, low-cost and robust against environmental perturbations.
