A control method of electron beam scanning track and scanning mode was put forward, in which the curvilinear equations describing the electron beam scanning track were established according to the shape of the actual welding seam, the size of scanning region, scanning mode etc.
提出一种电子束扫描轨迹和扫描方式控制方法 ,采用二维曲线来描述电子束扫描轨迹 ,根据实际焊缝的形状、扫描区域的尺寸、扫描方式等建立曲线方程 ,并对其进行离散化处理 ,然后经D/A转换产生所需的模拟信号 ,该信号经放大后输入给偏转线圈驱动电子束按设定的扫描轨迹和扫描方式运动。
Under the conventional CT scanning mode, some specimens with the flat-type can t fulfill the CT reconfiguration because they are failing to get the complete projection being restricted by the rotated space or detector s dynamic scope.
在常规的CT扫描方式下,对于一些形如扁平体的试件,通常受旋转空间或探测器动态范围的限制而得不到完整的投影,也就不能完成CT重构。
Since 45°rotation scanning mirror is the most mature and common photo-mechanical scanning mode, having the wide range of applications in the satellite remote sensor.
但是由于45°旋转扫描反射镜在扫描过程中会产生像旋,直接采用该扫描方式在应用于线列或面阵探测器并扫成像系统时会造成轴外视场的无法配准。
Various scanning mode is built in the system, which offers system-level support for the most common scan mode, a.
