摘要： The present invention provides a hologram which forms a light intensity distribution on a predetermined plane by using an incident light. The hologram includes a plurality of cells configured to control both a phase of a first polarized light component of the incident light and a phase of a second polarized light component. The plurality of cells are designed to form a portion in an overlap region in which a first light intensity distribution region formed on the predetermined plane by the first polarized light component and a second light intensity distribution region formed on the predetermined plane by the second polarized light component are superposed on each other. The phase of the first polarized light component is diffused in the portion formed in the overlap region.

摘要： An optical reproducing method. A diffracted light is generated by irradiating a reference light onto a hologram. A combined light is generated by applying a direct-current component formed by a polarized light having a third polarization component with a first polarization plane having a polarization direction orthogonal to the diffracted light and having the same phase as the diffracted light, and a fourth polarization component with a second polarization plane having an opposite phase to the diffracted light, onto the diffracted light. The combined light is separated into a fifth polarization component including a first polarization component and the third polarization component, and a sixth polarization component including a second polarization component and the fourth polarization component. A first reproduced image is reproduced from the separated fifth polarization component, and a second reproduced image is reproduced from the separated sixth polarization component.

摘要： An authenticity identifying film (10) has a reflective film (11) having a circularly polarized light selectivity to reflect at least only either of right-handed circularly polarized light and left-handed circularly polarized light of incident light to produce reflected light. The reflective film (11) is provided with a hologram forming part (11a). The hologram forming part (11a) reflects circularly polarized light of the same circular polarization as that of the reflected light in a direction different from that of the reflected light to form a holographic image. The reflected light reflected by the reflective film (11) and the holographic image formed by the hologram forming part (11a) are detected by detectors disposed at different positions, respectively.

摘要： An image exposure recorder for exposure-recording a holographic stereogram image or a hologram image on a recording medium for hologram. The recorder has an inverse correction system for rotating the polarization plane of a reference light (R) by means of a half-wave plate (11), directing the reference light (R) to a hologram recording medium (3), and measuring the intensity of a part of the reference light (R) transmitted through a polarizer (12) out of the reference light (R) transmitted through a part of the area of the hologram recording medium by means of a photodetector (13). In the inverse correction system, the angle of rotation of the half-wave plate is so determined that the intensity of the reference light (R) determined by the photodetector may be minimum or maximum. Therefore the degradation of the coherence between the object light and the reference light attributed to the transmission of the object and reference lights through the hologram recording medium having birefringence is prevented, and thus a holographic stereogram for reproducing a bright holographic stereogram image is fabricated.
摘要翻译：一种用于在全息图的记录介质上曝光记录全息立体图像或全息图像的图像曝光记录器。记录仪具有用于通过半波片（11）旋转参考光（R）的偏振面的逆校正系统，将参考光（R）引导到全息图记录介质（3），并测量通过借助于光电检测器（13）透射通过全息图记录介质的一部分区域的参考光（R）透射通过偏振器（12）的参考光（R）的一部分的强度。在逆校正系统中，半波片的旋转角被确定为由光电检测器确定的参考光（R）的强度可以是最小或最大。因此，防止由于物体和参考光通过具有双折射的全息图记录介质而导致的对象光和参考光之间的相干性的劣化，因此制造了用于再现亮全息立体图像的全息立体图。
