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。Computational flow imaging ( cfi ) uses theoretical predictions of the interaction and transmission of optical waves through theoretical flowfield to generate digital pictures that simulate real observations. it was used to construct flow visualization corresponding to shadowgraph, schlieren, interferometric and planar laser induced fluorescence ( plif ) images. by providing a better insight into the flow physics and cfd code behavior, cfi is proving to be extremely useful to experimentally validate cfd codes
計算光學流動顯示技術( computationalflowimaging - cfi )就是把數值計算( cfd )獲得的流場中的物理場,經過與實驗相同的計算光學(全息干涉、紋影、陰影、平面激光誘導熒光)的過程轉換為所需的各個方向與試驗流動顯示圖像相對應的計算流動圖像。The theoretical research, computer simulation and experimental results analysis show that maskless laser interferometric lithography and holographic lithography have the characteristics of large field of view, high resolution, distortionless, relatively simple system structure, low costs and convenient realization way. they have a broad application prospect
激光干涉光刻技術研究四川大學博士學位論文理論研究、計算模擬和實驗結果分析表明,無掩模激光干涉光刻和全息光刻具有大視場、高解析度、無畸變、系統相對簡單、成本較低,實現方便等特點,具有廣闊的應用前景。By using optical cable communication methods, which have advantages of great information transmission capacity, rapid velocity, wide frequency band, strong anti - jamming capability, low circuitry loss and easy construction, modern sky - wave over - the - horizontal radar can achieve information transmission and system control of full coherent radar, which has excellent abilities of security, stabilization, anti - jamming and anti - destruction
通過採用光纖傳輸技術,利用其信息傳輸容量大,速度快,頻帶寬,抗干擾能力強,線路損耗低,易於施工等特點,實現全相參雷達的信息傳輸和系統控制,具有優良的保密性,穩定性、抗干擾性和抗摧毀能力。( 4 ) applications of digital holography in optical metrology are briefly discussed. we also present the fundamental principles of digital holographic interferometry and the two ways to realize it. and also the difference between digital holographic interferometry and optical holographic interferometry is considered
( 4 )闡述了數字全息干涉術的基本原理和兩種實現方法,討論了其與傳統光學全息干涉術之間的聯系與區別,並根據數字全息術自身的特點,討論了諸如相位倍增因子等提高全息干涉計量精度的方法。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。In addition, from the point of view of practicality, we make a study of experiment and application for double - exposure digital holographic interferometry, namely measuring gradn and grad / i of plane optical flat and measuring phase modulation characteristic of a kind of liquid crystal spatial light modulator ( lc - slm ) - liquid crystal television ( lctv )
另外,本文還從實用的角度出發對二次曝光數字全息干涉術進行了實驗及應用的研究,具體就是平面平晶gradn和gradh的測量以及液晶空間光調制器( lc - slm )中液晶電視( lctv )的相位特性的測量。It indicates that digital holographic interferometry is a coherent optical technique, which allows the direct access to the interference phase. the measured interference phase contains information of the object field and its changes, so we can get the parameters changes according to the measured interference phase
指出,數字全息干涉術可以直接計算得到干涉相位差,並由干涉相位差準確地恢復出物場的待測物理參數,取得比光學全息干涉術更高的測量精度。In this paper, we apply the fourier transform method ( ftm ) of the phase analysis method to double - exposure holographic interferometry and propose double - exposure digital holographic interferometry
本文將相位分析技術中的傅立葉變換法( ftm )引入二次曝光全息干涉計量中,提出了二次曝光數字全息干涉術。However, the application field of optical holography technology has been restrained, for the lack of the high coherence and intensity of lights and the quite stable optical instrument
但是由於光全息技術要求具有高度相干性及高強度的光源、非常穩定的光學系統,因此限制了它們的應用范圍。分享友人
