Gerçek zamanlı holografik video üretiminin fpga uygulaması simülasyonu

Holography is a promising method for three-dimensional vision. Differentresearch efforts are being spent to improve generation of holograms and imagereconstruction from holograms. A computer generated hologram can be aprecise method of generating a real like video in the future. Rayleigh-Sommerfeld diffraction method and Fresnel-Kirchhoff diffraction formula aretwo algorithms suitable for FPGA implementation of hologram calculation.Simulator image reconstructions and optical image reconstructions with spatiallight modulator using the generated holograms are compared and it is seen thatthey are quite similar. A field programmable gate array (FPGA) implementationof real time holographic video generation based on Rayleigh-Sommerfeldformulation is simulated. FPGA implementation is tested and verified by acomputer simulator. An FPGA board capable of capturing video input andgiving video output for spatial light modulator (SLM) is chosen as theimplementation platform for simulations. A small size hologram calculator canbe implemented on the FPGA board. A custom board for specific hologramcalculation algorithm can be designed to increase the performance. Pipelinedarchitecture and SDRAM memories can be used to increase the performance.
