Some kinds of dye-doped-films have been used as a hologram in which an interference pattern is recorded through an irreversible photochemical change in absorption coefficient or refractive index, or both of them. In pure amplitude and phase holograms, the diffracted waves have the additive phase of zero and π/2, compared with the phase of the reading wave, respectively, while, in a mixed hologram, the additive phase may take a intermediate value but depends on the amplitudes of the object and reference waves. This additive phase may be added to the intrinsic phase of the object wave, so that in holographic and phase conjugate interferometries, it is important to know beforehand the value of the additive phase.We showed that the additive phase takes a constant value for low diffraction efficiency. We proposed how to measure the additive phase of the wave reconstructed from a mixed hologram. The additive phase is determined by measuring the contrast and the delay of the intensity changes of the two diffracted waves under the illumination of a moving hologram with two reading waves. We verified the validity of the proposed method by using some xanthen-dye- and spiro-dye-doped films.

一些种类的染料掺杂膜已被用作全息图，其中通过吸收系数或折射率或两者的不可逆光化学变化来记录干涉图案。在纯振幅全息图和纯相位全息图中，衍射波的附加相位分别为0和π/2，与阅读波的相位相比，而在混合全息图中，附加相位可以取中间值，但取决于物波和参考波的振幅。这种附加相位可以加到物波的本征相位上，所以在全息和相位共轭干涉术中，事先知道附加相位的值是很重要的，我们证明了在低衍射效率时附加相位取一个常数。提出了如何测量从混合全息图再现的光波的加性相位。加性相位是通过测量在具有两个阅读波的运动全息图的照明下的两个衍射波的强度变化的对比度和延迟来确定的。我们使用一些氧杂蒽染料和螺环染料掺杂的薄膜验证了所提出的方法的有效性。
