Various holographic recording media were compared for conditions of low signal energy densities. The peak value of diffraction efficiency divided by signal-beam exposure (Q) and of normalized contrast ratio divided by signal-beam exposure (A) for Kodak 649 F and for Agfa 8E70, 10E70, and 14C70 were determined. The quantities were optimized with respect to bleaching, hypersensitization, development, and reference beam exposure. Above some value of the reference-to-signal beam ratio these quantities were constant, while their dependence, if any, on the offset angle and signal beamwidth was not determined. The film response was considered in terms of the model T(a) = [b/(b + E(d))] (e) from which Q and A were calculated.
针对低信号能量密度条件，对各种全息记录介质进行了比较。确定了柯达649F以及爱克发8E70、10E70和14C70的衍射效率峰值除以信号光束曝光量（Q）以及归一化对比度除以信号光束曝光量（A）。这些量针对漂白、超敏化、显影和参考光束曝光进行了优化。在参考光束与信号光束比率的某个值以上，这些量是恒定的，而它们对偏置角和信号光束宽度的依赖性（如果有的话）未确定。根据模型T(a) = [b/(b + E(d))] (e)来考虑胶片响应，由此计算出Q和A。
