而且目前所研制的激光超声无损检测系统基本上采用外差干涉的方式,而零差干涉方式国内尚未见到有相关报道,这属于论文的主要创新点。 - This multi - purpose optical metering system had adopted the twyman - green interferometric system as its center , containing an advanced digital wave surface interferometry and a kind of homodyne interferometer displacement testing method with nanometer - sized capacity . at the same time , many wide - applied metering technology , for example , the diffracted field ( fringe ) measurement , co - focal lens system , optical fiber sensors and 4f ( focal distance ) space filter system which can embody the chief principle of fourier optics well , were combined into it successfully . this instrument can firstly offer and show modern optical testing method in the laboratory for majors of information processing , instrument science , measuring and testing technology and automatic technology
该多功能激光光电实验系统以泰曼-格林干涉( twyman - green )光路作核心，包括先进的数字波面干涉技术和一种基于空间干涉原理的、纳米分辨率零差干涉仪位移测量方法，同时将多种新颖、工程实用价值高的测量技术和光路如衍射测量、共焦显微技术、光纤传感技术以及反映傅立叶光学基本光学原理的4f空间滤波系统也组合进去。 - The channel capacity achieved in our experiments was better than that of the dual homodyne coherent state , homodyne coherent state and squeezed state communication when the average photon number exceed 0 . 99 , 1 . 11 and 2 . 06 respectively . it is more interesting that we found in the experiment , that the maximum channel capacity for a single mode - fock state communication can be surpassed with our system when the average photon number exceed 11 . 302
我们实验所得密集编码的信道容量在光子数大于0 . 99 、 1 . 11及2 . 06时将分别超过相干态双零差通讯信道容量、相干态零差通讯的信道容量以及压缩态零差通讯的信道容量；最重要的是，当平均光子数(
