束着靶
Examples
- Beam landing errors
电子束着靶误差 - Part 2 analyses beam landing shifts made by thermal deformations of a shadow mask and vibration of a new type of shadow mask - aperture grille . an automatic measurement system for cpt decolorization and a vibration measurement system for aperture grille are established . part 3 analyses the difference of perception and discrimination to color between the human eyes and ccd system , and develops a new method based on ccd technology to evaluate the screen white - balance
主要内容分为三部分: ( 1 )分析着屏电子束分布与电子枪、偏转系统及荫罩之间的关系,研制自动测试装置,为设计和改进相关结构提供依据; ( 2 )分析荫罩热变形和振动对显示屏色纯度影响,建立了色纯漂移自动测试装置和张紧式荫罩振动测试系统; ( 3 )分析了人眼与ccd对彩色刺激的不同响应,建立了基于ccd的显示器全屏色纯均匀性测试方法。 - Aberration of electronic lens made by electron gun and aberration of magnetic deflection system made by dy are comprehensively investigated , so is the shadow mask ' s effect on electron beam landing screen error . the conclusion can be get that , because the distribution of electron beam landing screen ( distribution of luminance ) is affected by many kinds of factors , it cannot get the correct function by calculation , and should be get by measurement instead
全面分析了cpt电子枪发射系统形成的电子透镜像差与磁偏转系统形成的偏转像差;分析了荫罩的自身厚度与位移对电子束着屏的影响,并由此得出结论,着屏电子束分布(即亮度分布)受着许多因素的影响,理论分析是半定量的,着屏电子束分布需要用精确的测量仪器来测量。 - By using auto - adjusting boundary conditions and the method of three cubed spline curve fitting , the system software can recover both of the horizontal and vertical beam profile . the measurement system can also measure the beam landing screen error of cpt . it provides a important measurement and analysis tool to improve the performance of electron gun and dy , and improve the definition of cpt
系统软件中,提出了采用动态确定边界条件,通过对离散采样点的三次样条插值曲线的拟合恢复束斑x和y方向的轮廓,本系统既能准确客观地描述电子束轮廓,又能够准确快速地测量电子束着屏误差等多种参数,为cpt电子枪和偏转系统的性能改进与分辨率的提高提供了有力的测试分析和研究手段。
