Various implants are employed to recover the function of the femur by providing mechanical fixation. However, these implants can have a very limited life and require replacement. In order to optimize implant life, it is necessary to improve the design of components and implantation techniques, which is clearly also beneficial to both patients and hospitals. The determination of the real displacement patterns across implanted bone is important in developing alternative and improved implants. Holographic interferometry, a displacement analysis technique permitting whole-field inspection of deformation patterns, was used as the experimental method. In this study, a one-shot holographic interferometry is developed for simultaneous measurements of three aspects of femur. The optical system consists of two sets of plane mirror each arranged to face the postcrior and antcrior of fcmur. Three objective images reconstructed from holograms are constructed in the CAD system and analyzed. By the proposed method, experiments become easy and the reliability of the data is improved. The feasibility of proposed method is shown by measuring displacement of the intact model bone.
