例句與用法
- Off - axis hologram
離軸全息圖 - This method has some characters : during recording of the transmissive holograms the holographic grating placed in front of the holographic plate closefittingly is used as a spectroscope . the transmissive wave is served as the object wave and the diffraction wave through the holographic grating or the deflective reflect wave produced by the silicon slice is served as the reference wave , therefore the hologram is named as self - reference image hologram . the recording results are the off - axis holograms and the twin images can be separated successfully
在記錄透射型全息圖時，將全息光柵緊貼置于記錄干板之前，而光柵起到了分光的作用，直透波作為全息圖的物光波，參考光是物光通過光柵后產(chǎn)生的衍射波；記錄反射型全息圖時將硅片置于記錄干板之后，利用反射硅片產(chǎn)生離軸參考光，因此系統(tǒng)僅需一束照明光束，參考光來自物光本身，因此稱之為自參考像全息圖。 - This is the first generation holograph . aided by an abundance ot the new coherent laser light and extended by a number of technological advances , leith and upatnieks produced the off - axis hologram recorded and reconstructed by laser in 1962 . the twin images can be separated in this hologram
隨著高相干度激光的出現(xiàn)， 1962年leith和upatnieks將通訊理論中的載頻概念推廣到空域中提出激光記錄、激光再現(xiàn)的離軸全息圖，分離了孿生像，使全息術(shù)進(jìn)入了第二代全息圖的發(fā)展時期。
