提出了一种新的全场高度映射方法，利用激光片光产生的莫尔条纹的性质，拟合出两个映射曲面。通过这两个曲面方程，可同时直接得出ＣＣＤ探测器表面任意一点在实际世界坐标系中对应的高度和一维横向坐标。此方法具有极大的实用价值 A new method of global height mapping is proposed. By using the properties of moire fringes produced by laser light, two mapping surfaces are fitted. Through these two surface equations, the corresponding height and one-dimensional transverse coordinates of any point on the surface of the CCD detector in the actual world coordinate system can be directly obtained at the same time. This method has great practical value
