我們利用球面波位移技術與共軛光讀取架構結合體積全像的繞射特性,設計一高儲存容量與高傳輸速度的光學儲存系統。因為讀取光與參考光的相位不匹配,即讀取光微小位移將使得繞射強度快速地衰減,因此系統將發展出具有高儲存容量的特性。當此儲存系統之訊號輸入元件為一空間調制器,因此系統將擁有光學平行處理的能力,增加訊號的傳輸速度。另外,當碟片在布拉格不匹配條件下,我們能精準的控制且預測繞射光偏移之情形,甚至使得繞射光在觀察面上不偏移,而使得繞射光之畫素與畫素間之串音在此情況下為最小。
論文中以相位疊加法分析體積全像的繞射訊號,研究其繞射訊號特性與系統的位移容忍度,並分析畫素間之串音,並有效的控制串音,使其對系統之影響降為最低,並期能實現且解決體積全像儲存之困難。
