Typical computer generated holography ( cgh ) and hologram synthesis that simulate typically optical holography need to compute a huge 2-d holographic fringe, or to lose some 3-d information and resolution to reduce data . the first real-time display of holographic images was reported in 1990 by the mit spatial imaging group . but this is still an open problem because view angle of holographic images, volume and speed of transmit are limited 傳統(tǒng)的研究集中在計算機生成全息圖(computer-generatedholography,簡稱cgh)和全息圖綜合的方法上,采用模擬光全息的物理方法,從而導致數(shù)據(jù)量龐大,無法在現(xiàn)有硬件上完成實時處理,或者靠損失部分三維信息和分辨率以減少數(shù)據(jù)量,但失去了真三維顯示的效果。
