However, ordinary polarization recording geometry configuration is more property to gain better uniformity of diffraction efficiency. 而o光耦合(写入光均为寻常偏振)的方式有利于获得更佳的衍射效率均匀性。
Methods Recording was performed with very low noise, high gain amplifiers and by analog filtering. 3-brigade amplifiers and 16-bite A / D were connected to a microcomputer by USB. The signal was processed by a combined pattern recognition and digital filtering software. 方法使用极低噪声3通道高增益放大器,16位A/D转换,通过USB接口与微机连接,采用模式识别和数字滤波联用软件对微信号进行处理。
To use the airborne multimedia scene recording system is a high, effective and feasible method to gain airborne picture and data. 机载多媒体现场记录系统是实现机载图像和数据获取的一种高效可行的方法。
Thus, multi-channel MPEG-4 surveillance recording system with high resolution, excellent stability and low cost, which is developed by using embedding technology, can gain the technology advantage in the world but also with great rivalship. 因此用嵌入式开发出的高清晰度、稳定的、多路的、低成本的MPEG-4监控录像系统不仅会在当今世界取得技术领先的优势,还可以形成极大的产品竞争力。
It records the intensity information of interferograms digitally by using optoelectronic recording device such as Charge Coupled Devices ( CCD ), stores it in a computer, and then processes the data by corresponding algorithms to gain the information of the original object. 它利用电荷耦合器件(ChargeCoupledDevices,简称CCD)等光电记录器件以数字化的方式记录全息干涉图的强度信息并输入计算机,使用相应算法进行数据处理,获得原始物波信息。
