Theoretical expressions are derived describing the process of writing volume (or thick) hologram gratings in photochromic materials. The theory includes the effects of the saturation of the material response, scattering of the writing beams by the partially written hologram, and the refractive index changes that accompany the photoinduced absorption changes. Results of representative numerical calculations are presented and interpreted in terms of simpler models and approximations. Use of the results is illustrated by the calculation of the holographic characteristics of an actual material. The results are also related to model photochromic systems to estimate the range of achievable holographic characteristics and to obtain an approximate procedure to estimate the absorption spectra of materials that would give specified holographic characteristics.
推导了描述在光致变色材料中写入体（或厚）全息光栅过程的理论表达式。该理论包括材料响应饱和的影响、部分写入全息图对写入光束的散射以及伴随光致吸收变化的折射率变化。给出了代表性数值计算结果，并根据更简单的模型和近似进行了解释。通过计算实际材料的全息特性来说明结果的应用。结果还与模型光致变色系统相关，以估计可实现的全息特性范围，并获得一种估计能给出特定全息特性的材料吸收光谱的近似方法。
