提出了一种制作具有预期位相调制度的卤化银乳胶位相型薄全息光栅的方法。它通过分析所拍摄的第一张全息光栅的数据来获得最佳曝光参量，从而使继后的拍摄，在同样的实验条件下能获得所预期的位相调制度。文中给出了这方法的理论分析和某些应用。 A method of fabricating a silver halide latex phase-profile type thin holographic grating with the desired phase modulation is proposed. It obtains the best exposure parameters by analyzing the data from the first holographic grating taken so that subsequent shots can achieve the expected degree of phase modulation under the same experimental conditions. The paper gives the theoretical analysis of this method and some applications.
