Abstract
Digital holography has become a powerful method for measuring three-dimensional topography of complex shapes. The application of optical-fibers can make the system more compact and flexible. However, some problems are also brought into the system by the use of optical-fibers. In order to facilitate the analysis and optimization of the measurement system, the digital holographic interferometry system is simulated in the optics software which is based on field-tracing. This allows the seamless combination of different numerical analysis techniques in different subdomains of the system. The fiber coupling efficiency is optimized. Hereby the parameters of the coupling lens and the splitting ratio can be determined. Finally the object wave is reconstructed from the interferograms, which verifies the reliability of the optimization results.
