This method depends on duplication of information-carrying optical waves which come from a threedimensional environment in the absence of the original source. Computation of the diffraction pattern due to an object is the most important process in digital holography. The diffraction pattern due to an object can be calculated by using several methods. Two models are generated and they are based directly on Rayleigh-Sommerfeld diffraction integral; there is no need for Fresnel or Fraunhofer approximations. The generated models are used to calculate scalar optical diffraction between tilted planes for monochromatic light. First model we generate is called pointwise model. The model provides calculation of the diffraction pattern on an observation plane by superposition of the diffraction patterns of the point light sources that made up the object on a input plane. However, it is a time consuming process. Second model is named plane wave spectrum model and it is much more faster than the pointwise model. The performances of the presented models are examined under several scenarios.xiii, 120 leaves, illistrationsEnglishinfo:eu-repo/semantics/openAccessDigital Holography3-D ObjectsFresnel DiffractionScalar Optical DiffractionPlane Wave Spectrum DiffractionTA1540 .E86 2004Holography.ThesisBILKUTUPB083121
