This is the second generation holograph. since the hologram reconstructed by laser loses the hue information, benton produced two - step rainbow holography in 1969, which gave the hologram vivid colors. this is the third generation holograph
由於激光再現的全息圖失去了色調信息, 1969年benton提出二步彩虹全息術,在一定的條件下賦予全息圖以鮮艷的色彩,形成激光記錄、白光再現的第三代全息圖。Because color isochromatic fringes appear in the stress model based on a plane polariscope in white light, we studied the problems systematically by a digital camera as image inputting device, digital image processing technique and bp artificial neural network. based on the work that has been reported before, a technique named five - step color phase shifting technique ( fcpst ) to acquire single isoclinics is presented
根據白光入射時應力模型在偏振儀光學系統中的等色線條紋是彩色的特點,本論文採用彩色數碼相機作為數據採集與輸入設備,結合彩色信息圖像處理和bp神經網路等新技術,對上述兩個難題進行了系統的研究,獲得以下成果:在綜合前人工作的基礎上,提出獲得全場單純的等傾角相圖的五步彩色相移法。The influences of recording conditions on the snr of the black - white digital images retrieved from fourier transform holograms were experimentally studied. the holograms were recorded on photoresist plates using an electrical addressed tft - lcslm as a data input device, and a normal ccd camera was applied for detecting reconstructed images
採用電尋址液晶空間光調制器作為存儲系統的組頁器,常規ccd探測器作為重構圖像的檢測器件,實驗研究了在光刻膠干板上記錄黑白二值條紋圖像的傅里葉全息圖時,記錄條件對重構圖像信噪比的影響。Furthermore, three fourier storage schemes were proposed for practical anti - counterfeiting : ( 1 ) store black - white digital images with hidden information made by image coding method, ( 2 ) store several images on the same spot with reference beams of different directions ( peristeophic multiplexing ), ( 3 ) store a serious of given images recorded closely ( space multiplexing ). three different fourier holograms were recorded on photoresist plates following the above three schemes using the optimized recording conditions obtained in the first part of this study work. the reconstructed images form the holograms showed some special anti - counterfeit effects
此外,本課題還研究了傅里葉全息存儲在防偽上的實際應用,提出了三種防偽存儲方案: ( 1 )運用圖像編碼方案,存儲了具有隱藏信息的編碼黑白二值圖像; ( 2 )運用旋轉復用方案,在同一存儲點用不同方向的參考光存儲了多幅圖像; ( 3 )運用空間復用技術,在一定區域內緊靠著記錄一系列特定圖像的傅里葉全息圖。In the last part, we give the theoretical deduction and the experiment setup of the two self reference image holograms of the original objects illuminated by incoherent light, the principle is alike with the former
基本原理與採用相干光時相同,同時也給出了實驗裝置,推導出全息圖再現像的位置,展示了根據再現像拍攝出的黑白照片。分享友人
