分析了用光刻胶记录激光散斑来制作粗糙度参数可控表面的方法，并成功地制作了一批样品。这些样品表面具有连续平滑的起伏轮廓，符合粗糙表面散射研究的理论模型，也可用作相位板。

A method of fabricating rough surfaces of known statistical parameters by exposing the photoresist to laser speckle patterns is analysed in this paper. A set of samples have been made successfully. These surfaces have a smoothly modulated profile which is amenable to the theoretical model of rough surface scattering. These specimens can also be used as phase screens.
