入瞳 meaning in Chinese

entrance pupil

The results show the light rays nearby the center of the objective back aperture have greater contribution to the transverse forces , while those nearby the edge affect mainly the axis forces
计算与分析表明，靠近物镜入瞳中心的光线对横向光作用力的贡献较大，而靠近物镜入瞳边缘的光线对纵向的光作用力贡献较大。
Image coordinate and galvanometer pendular angle are kept in the computer according to the f9 field lens characteristic , enter pupil excursion and f6 characteristic error are ignored , that the image of laser scanning point move acceding to unlinearity relation is deduced theoretically . for deducing the distortion , error compensation is considered in the software
像点坐标与振镜摆角按f物镜特性的线性关系存储在计算机，在忽略了入瞳漂移和f特性误差后，从理论上推导出二维垂直振镜分布中激光束扫描点的像点按照复杂的非线性关系运动，为了减少几何畸变，在软件设计中给出误差补偿。
