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 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。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。分享友人
