    • In a holographic information recording and reproducing apparatus, an optical fiber guides a reference beam toward a recording medium for holographic recording, and a precision rotator is turned, so that the reference beam is incident on the recording medium at different angles and interferes with a data-carrying signal beam to complete the recording of holographic information on the recording medium. To reproduce the holographic information, the optical fiber guides a reading beam, and the reading beam is incident on the recording medium at an angle the same as the reference beam for the recording to reproduce the holographic information stored on the recording medium. With the optical fiber and the precision rotator, a simplified light path system and a wide range of incident angles for the reference and reading beams may be achieved, and the transmissive, reflective, and 90-degree holographic storage techniques may be integrated in one single apparatus.
    • 在全息信息记录和再现装置中,光纤将参考光束引导到用于全息记录的记录介质,并且旋转精密旋转器,使得参考光束以不同的角度入射到记录介质上并干扰数据 携带信号光束以完成记录介质上的全息信息的记录。 为了再现全息信息,光纤引导读取光束,并且读取光束以与用于记录的参考光束相同的角度入射到记录介质上,以再现存储在记录介质上的全息信息。 利用光纤和精密旋转器,可以实现简化的光路系统和用于参考和读取光束的宽范围的入射角,并且透射,反射和90度全息存储技术可以集成在一个单一的 仪器。
