Specific features of spectral properties of volume reflection holograms are determined, namely, broadening of the spectral response (reflex) contour toward both the short-wave and long-wave spectral ranges in the case where the angle of incidence of the white-light probing beam differs from the direction of reference wave propagation in hologram recording. This effect is essentially different from the known angular dependence of the reflex of the elementary volume reflection grating. A theoretical explanation for experimental data is provided, and formulas are derived, which are used to calculate the transmission spectra of the studied gratings. These spectra are found to be qualitatively consistent with the experiment.

漫反射物体的体反射全息图的光谱特性的具体特征

确定了体积反射全息图光谱特性的特定特征，即在白光探测光束的入射角改变的情况下，光谱响应（反射）轮廓向短波和长波光谱范围的展宽与全息记录中的参考波传播方向不同。这种效应与基本体反射光栅的反射的已知角度相关性本质上不同。给出了实验数据的理论解释，并推导出了公式，用于计算所研究光栅的透射光谱。发现这些光谱与实验定性一致。
