recorded hologram 中文意思是什麼
-
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， 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、激光再現的離軸全息圖，分離了孿生像，使全息術進入了第二代全息圖的發展時期。 -
After analyzing the experiment, the author completes designing the experiment in which the fresnel hologram is recorded with ccd. how to realize the technology with program is the focus of the research
作者針對全息圖記錄中低的ccd解析度，合理地分析了實驗條件，完成了應用ccd直接記錄菲涅爾全息圖的實驗設計。 -
In order to investigate the phenomenon that holograms tend to be deteriorated on baing recorded in photopolymers with shrinkage, a fourier hologram is taken with slant gratings formed by the reference beam and object beams of different space - frequency
摘要為了分析光致聚合材料記錄的譜面全息圖在再現過程中發生「擦除」現象，將譜面全息圖看作由不同角譜的物光與參考光在光致聚合材料內形成的不同傾斜角度的光柵總和。 -
The high relativity of lasers limits the actual applications of the holographic technique, they began to probe the forth generation hologram recorded and reconstructed as well by white light
為了克服激光的高度相干性給全息技術的實際使用帶來的種種不便，又繼續探討白光記錄的可能性。 -
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。
