    • A hologram reproduction apparatus comprises a first optical system disposed on one side of the hologram recording medium to form an optical path of the reproduction reference beam using the same optical path as that of the recording reference beam; a second optical system disposed on the data beam optical path on the other side of the hologram recording medium that is opposed to the one side to receive a diffracted light obtained by causing the reproduction reference beam to strike on the one side of the hologram recording medium from the one side of the hologram recording medium and load captured image data corresponding to the image data; and a control unit operable to carry out an inverse Fourier transform process on the captured image data loaded into the second optical system.
    • 全息图再现装置包括设置在全息图记录介质的一侧的第一光学系统,以与记录参考光束相同的光路形成再现参考光束的光路; 第二光学系统,设置在全息图记录介质的另一侧的数据束光路上,与该一面相对,以接收通过使再现参考光束照射在全息图记录介质的一侧而获得的衍射光 从所述全息图记录介质的一侧加载与所述图像数据对应的拍摄图像数据; 以及控制单元,用于对加载到第二光学系统中的捕获图像数据执行逆傅立叶变换处理。

    • A tilt detection apparatus for a medium comprises a tilt detection beam generator that makes a tilt detection beam incident ion a medium to detect whether the medium is tilted with respect to a reference position; a light reception unit that receives the tilt detection beam that after striking the medium, has come from the medium; and a correction output unit that outputs a signal to correct a tilt of the medium, based on a difference in light reception position on the light reception unit between a position at which the light reception unit receives the tilt detection beam and a position at which the light reception unit is to receive the tilt detection beam when the medium is in the reference position.
    • 用于介质的倾斜检测装置包括倾斜检测光束发生器,其使倾斜检测光束入射离子介质以检测介质是否相对于参考位置倾斜; 光接收单元,其接收在打印介质之后来自介质的倾斜检测光束; 以及校正输出单元,其基于光接收单元接收到倾斜检测光束的位置和光接收单元接收到倾斜检测光束的位置之间的光接收位置的差异,输出用于校正介质的倾斜的信号 光接收单元在介质处于参考位置时接收倾斜检测光束。
