杨氏干涉场中干涉条纹的梯度解

GRADIENT SOLUTION OF THE INTERFERENCE FRINGES IN A INTERFERENCE FIELD

在把光的干涉在空间强度钓稳定分布看作为稳定的标量场的前提下,研究了空间干涉场,从而得到了干涉场强度梯度方向与光程差梯度方向是一致的的结论。进而得出平面干涉场强度梯度是空间干涉场强度梯度在这个平面上投影的推论。这个推论使平面干涉场梯度计算变得方便。

In this paper the stable distributiou of the space intensity in the opti- cal interference has been regarded as a stable scalar field.The research on the interference field of space was based on this idea.The conclusion has been got that the gradient direction of the intensity of the interference field is identified with the gradient direction of the optical path difference, It is further deduced that gradient of the plan interference field is the projection of the space interference field on that plan.And this makes it more convenient for the calculation of the gradient of the plane interference field.
