This paper presents a new method which is called panoramic Moire'topography. This method can take a 360°panoramic topography of an object with asynchronous slit camera while the object is rotating about its center relative to afixed flat grid. The principle and method about how to generate a panoramic topo-graphy is described. The formulas, the error analysis of contouring fringes and theexperimental devices are explained. We get the panoramic topography of the "boy'shead" model and the conic cylinder by this method. The comparision of the expori-mental values of the conic cylinder with the theoritical values shows that the erroris less than ± 0.05mm.

全景莫尔轮廓法是一种新的方法。这方法的原理是通过被测物体相对于某平面光栅的旋转,采用同步狭缝摄影机记录,获得物体360°圆周的全景莫尔轮廓图。文中介绍了全景莫尔轮廓图的形成原理和方法,以及莫尔等高线的计算公式和误差分析;描述了实验方法,装置及在实验中注意的问题。同时拍摄了“小孩头像”模型和圆锥体,获得了满意的全景莫尔轮廓图照片。对所得的轮廓图进行判读和计算。还将圆锥体的计算值和按锥度计算得的理论值进行比较,两者十分吻合,误差小于±0.05mm。

本文对狭缝相机测量目标速度的公式: V_0=l/l′V_F (1) V_0=tgφ·V_F/M (2)进行了分析;讨论了影响测量精度的因素。用X—70狭缝摄影机对目标进行了多次拍摄,得到了翔实的实验数据,并对数据进行了处理。根据(1)式计算的目标速度与速度的标定值作了比较;扫描拍摄时,根据(2)式计算的速度与自由落体运动的理论速度进行了比较。得出了XF—70狭缝相机作同步摄影时,其测量速度的相对精度达0.2%。用作扫描摄影时,其速度测量精度相对达0.8%的结论。
