摘要: | 本論文探討使用空間光調制器顯示電腦全像片,並經由遠場繞射成像之
投影顯示系統研究。我們分別使用遞迴傅立葉演算法以及對稱遞迴傅立葉
演算法設計電腦全像片,再經由遠場繞射之傅立葉轉換即可成像。我們以
電腦模擬其成像特性,並架設光學成像系統驗證之。最後根據實驗結果,
分析此投影顯示系統的限制及可行性。 n this thesis, we discuss a projection display system by use of computer generate hologram(CGH). A Kinoform CGH is designed by the iterative Fourier transform algorithm and symmetrical Iterative Fourier transform algorithm. And use Fourier transform reconstruct image from far-field diffraction. We simulate the characteristics of reconstruction image and set up a imaging system to verify the result. Finally we analyze the feasibility and restrict of the imaging system. |
