记录全息图 meaning in Chinese
recorded hologram
Examples
- ( 2 ) the serious recording limitations due to the finite size and resolution of ccd are discussed detailedly . it ' s shown that the setup for recording hologram with spherical reference wave can make full use of the spatial bandwidth of ccd
( 2 )着重讨论了ccd参数对记录条件的限制，给出了数字全息术所能记录的物体的最大尺寸与记录距离之间的关系，指出用球面参考光波记录全息图可以更为有效地利用ccd的有限带宽。 - 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。 - 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
本论文的研究发现，由于后记录全息图的写入光束对先存全息图的擦除效应，如果采用等时曝光法记录几百至上千幅全息图，那么相关点亮度将会变得均匀不一，后存比先存全息图的相关点总体上要亮，而采用顺序曝光法来记录全息图，就可以消除由擦除效应带来的相关点亮度不均匀的问题。 - Digital holography is a new imaging technique that uses a charge coupled device ( ccd ) camera for hologram recording and a numerical method for hologram reconstruction . this paper presents the concept and underlying theory for digital holography and its applications in 3 - d object reconstruction and optical metrology
