On the assumption of the exponential decrease, the coupled wave theory is applied to the calculation of the diffraction efficiency of the gratings. The comparisons between the calculation and the measurement are described about the relative diffraction efficiency and a condition to reduce the decrease of the grating modulation is discussed in terms of the recording parameters., Article, 信州大学工学部紀要 36: 23-34 (1974)}, pages = {23--34}, title = {厚さ方向にモジュレーションが変化するホログラムグレーティングの回折効率}, volume = {36}, year = {1974} }
