In this paper, the research on vignetting is done and a formula for vignetting about field angle、entrance window, entrance pupil and the distance between them is deduced.

文中对渐晕做了一些研究，并推导出一个渐晕关于视场角、入瞳、入射窗以及两者之间距离的解析式。

Speckle is also the fundamental uncertainty factor in this kind of sensors. The analytic expression of centroid uncertainty limit is derived from the statistic of laser speckle, and it is shown that the uncertainty limit in RST, and also in anamorphic triangulation, is dependent on the solid angle subtended by entrance pupil as seen from the illuminated laser spot, the triangulation angle, as well as the laser wavelength. The influence of aberration of optical system and surface roughness are also discussed.(4) A method of getting the 3D edge characters based on the integrated vision system is studied.

重点研究了RST中的激光散斑现象，从散斑统计学的角度，首次推导了激光散斑引起的旋转对称三角法位移测量不确定度的极限，结果表明在光学粗糙表面上，该极限由投射激光波长，光学系统入瞳对投射光斑所张的立体角，以及光学系统主光轴与旋转轴的夹角确定；这一结论同样适用于其他变形成像的激光三角法。4基于RST的工作方式，研究了利用集成视觉系统的扫描移动来获得被测物体的低分辨率三维信息的方法。

Drift entrance pupil in laser scanning system is studied in this paper, detailing in rotated octahedron mirror.

在近代激光测试技术中多面体旋转反射扫描测试系统存在入瞳漂移的问题，带来测试误差，然而经典资料中均未作讨论。

The results show that the speckle number is only determined by the relative size of the speckle cells and the area of the entrance pupil.

在激光散斑数和光电子数较大的情况下，以往的文献一般认为光电子数服从高斯分布。
