摘要
提出了在使用五孔剪切相机研制二阶微分场时，通过采用两次全场滤波技术可消除夹在二阶微分条纹中的一阶微分条纹，从而使二阶微分条纹具有较高的对比度。
Abstract
In this paper, the five aperture shearing camera used for measuring second order derivatives of objects is presented. The pure second order derivatives of objects can be obtained by using the double whole field filtering technique.
