They are holograms projected into the rooms from outside . 它們都是從房間外面投射到房間里的全息照相。
Some people have suggested that holograms should be made of all famous works of art . 有人建議把所有著名的藝術(shù)品拍攝成全息照相。
The resulting pattern was something he called a hologram after the greek word holos meaning whole . 所得到的圖樣他稱之為全息圖(hologram),這個字來自希臘字holos意思是“全部”。
Among other things, they introduced an improved arrangement for generating holograms which is illustrated in fig 14. 36 . 他們除了別的東西以外,還引入了一種產(chǎn)生全息圖的改進(jìn)裝置,如圖1436所示。
Admittedly, it is not at all obvious that by now shining a plane wave through the processed hologram one could reconstruct an image of the original object . 當(dāng)然,我們還根本看不出,用一個平面波照射處理后的全息圖,為什么能再現(xiàn)原來物體的一個象。
