This paper is trying to combine computer - generated hologram and digital holography together , to give the stimulated algorithm of the fresnel diffraction and through computational stimulation generate the hologram , which will reconstruct the original image , and ultimately , realize the numerical reconstruction of the hologram 本文嘗試將計算全息與數字全息相結合,研究光線的菲涅耳衍射傳播的模擬算法,用計算機模擬生成全息圖,并由所生成的全息圖再現出原始圖像,實現全息圖的數字重現。
By combining the advanced computer technology and optical holography technology together , computer - generated hologram can generate holograms , which , with no demand for objects , can be reconstructed through optical ways after the computer has processed the mathematical description of object waves 計算全息是將先進的計算機技術和光全息術結合起來,利用計算機產生全息圖。它不需要物體實際存在,而是把物波的數學描述輸入計算機處理后,繪制出全息圖,然后用光學方法重現。
First , by using coordinate rotation , we have discussed the computer - generated hologram composed by planar object whose plane does n ' t run parallel with that of its hologram . second , through coordinate transform , the computer - generated hologram of curvy planar object has been discussed again , in which , conformal map in computer graphics has been creatively applied , and generated the computer - generated hologram of simple curvy plane ( e . g . spherical surface ) ; also , in this section , the correctness of transformation has been confirmed by numerical reconstruction 首先利用坐標旋轉討論不平行于全息面的平面所構成的物體的計算全息圖:接著采用坐標變換討論曲面物體的計算全息圖,創造性地將計算機圖形學中的共形對應原理運用到計算全息中,生成了簡單曲面(如球面)物體的計算全息圖,并用數字重現驗證了變換的正確性,為今后復雜三維物體的計算全息圖的研究奠定基礎。
