referenced wave meaning in English
参考波
Examples
- Coded reference wave hologram
编码参考波全息图 - The basic principle of digital holography is that , by replacing the ordinary films with ccd , the hologram of the object and the reference waves can be obtained and reconstructed by numerical computing
数字全息的基本原理是用光敏电子元件(如ccd )代替普通照相记录介质，获取物体和参考光的干涉全息图，然后用数字计算方式再现。 - ( 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。 - This method has some characters : during recording of the transmissive holograms the holographic grating placed in front of the holographic plate closefittingly is used as a spectroscope . the transmissive wave is served as the object wave and the diffraction wave through the holographic grating or the deflective reflect wave produced by the silicon slice is served as the reference wave , therefore the hologram is named as self - reference image hologram . the recording results are the off - axis holograms and the twin images can be separated successfully
在记录透射型全息图时，将全息光栅紧贴置于记录干板之前，而光栅起到了分光的作用，直透波作为全息图的物光波，参考光是物光通过光栅后产生的衍射波；记录反射型全息图时将硅片置于记录干板之后，利用反射硅片产生离轴参考光，因此系统仅需一束照明光束，参考光来自物光本身，因此称之为自参考像全息图。 - The holographic wavefront recording process records the interference pattern of the object and the reference waves , and thus forms the hologram , which simultaneously records the information about the amplitude and phase of the object waves ; the holographic wavefront reconstruction , by means of the diffracted waves , can reconstruct the original object wave from the hologram illuminated by lights
全息波阵面记录将物光和参考光以干涉条纹记录成全息图，此全息图同时记录了物光波的振幅和相位；全息波阵面重现，就是用光波照射全息图，通过光的衍射，从全息图中再现出原始物体的光波。
