  • Abstract 摘要
                         
    圓盤型複合全像是由本實驗室蘇威宏.張瑞城學長,在1995年所發展出來的,但其二維物像若未事先修正,重建影像會有嚴重的扭曲。而且由於圓盤型複合全像片把每個角度的物體資訊,分別記錄成一條細長型的全像片,因此重建之影像,會有一條條的垂直條紋重疊在其上,此即所謂的「柵欄效應」。上述問題於1999年,由本實驗室陳志宏學長所提出的「成像面圓盤型複合全像」成功地解決了。以上所述的全像片均受限於系統上的設定,使得觀賞視窗相當有限,無法同時提供多人觀賞,故本人在論文中提出「可環繞觀賞之成像面圓盤型複合全像術」以改善此一缺點。
    本論文的重點在於,改變物光系統之入射角度,使得繞射出的二維影像能與視角作搭配以產生三維影像,並計算出物光入射角與LCTV旋轉角之間的關係,也事先計算出兩張全像片最大旋轉角度的間距,如此一來不但可以預防暗紋產生,也能使在無暗紋的情況下讓全像片上單點繞射效率達到最大。接著,分析傳統型與成像面型全像片繞射效率的差別,而後利用所定義之標準差分析所重建出的全像二維影像,並利用視線交會點理論模擬出三維影像,藉此探討各係數對所重建之三維影像的影響。以逆光路系統算出變形之原始二維物像,利用這些二維物像拍攝出變形極小的虛擬影像。
