optical holography meaning in English
光学全息术
Examples
- It is impossible to realize dynamic and real - time display for typical optical holography where there are two independence courses of optical holographic recording and optical holographic display
经典的光全息由波阵面记录与重现这两个独立过程构成，因此无法实现全息显示的动态和实时性。 - 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
但是由于光全息技术要求具有高度相干性及高强度的光源、非常稳定的光学系统，因此限制了它们的应用范围。 - Based on light interference , diffraction and optical holography theory , the paper comprehensively describes the basic principle , main types , development trend as well as the objective and significance for carrying out the research of laser maskless interferometric lithography and holographic lithography
本论文基于光的干涉和衍射及光学全息照相理论，综合评述了光学光刻的基本原理、主要类型、发展趋势及开展激光无掩模干涉光刻和全息光刻研究的目的和意义。 - Digital holography is a novel imaging technique which uses high - resolution ccd - cameras as hologram recording medium and reconstructs the image with numerical method . it involves optical holography , computer science , electronic technology and digital image processing . in recent years , particle analysis with digital in - line holography is an active research field
数字全息术用ccd记录全息图，以数值的方法再现全息图，它综合了光学全息原理、计算机技术、电子技术以及图像处理技术，是一种新颖的全息成像技术，具有处理简便、对实验环境要求较低、可实现准实时处理等优点。 - By combining the advanced computer technology and optical holography technology together , computer - generated hologram can generate holograms , which , with no demand for objects , can be reconstructed through optical ways after the computer has processed the mathematical description of object waves
计算全息是将先进的计算机技术和光全息术结合起来，利用计算机产生全息图。它不需要物体实际存在，而是把物波的数学描述输入计算机处理后，绘制出全息图，然后用光学方法重现。
