According to the previous studies a new technique for recording hologram is proposed in this thesis
目前有關全息術的研究主要集中在對傳統記錄方法的改進和研究探討其應用潛力和應用領域等方面。 -
Owning to the erasing effect, the correlation spots have not the same brightness if the holograms were exposed with the same times while recording. the correlation spot that related to the late recorded hologram is brighter than that related to the previous one. this problem can be solved by a subsequence exposure technique using in holograms receding
本論文的研究發現，由於后記錄全息圖的寫入光束對先存全息圖的擦除效應，如果採用等時曝光法記錄幾百至上千幅全息圖，那麼相關點亮度將會變得均勻不一，后存比先存全息圖的相關點總體上要亮，而採用順序曝光法來記錄全息圖，就可以消除由擦除效應帶來的相關點亮度不均勻的問題。
