摘要： Light emitted from a coherent light source undergoes fine adjustment of its polarizing direction by a polarizing device and is directed to a liquid crystal device through a collimating optical system. The polarizing device is capable of fine-adjusting the polarizing direction in accordance with the wavelength of the incident light, thereby providing a high contrast ratio. When an image is recorded by holography using such a liquid crystal spacial light modulator, it is possible to obtain an image of high quality.

摘要： A linearly polarized light beam emitted from a coherent light source reaches a polarizing phase plate and is thereby divided into a primary beam and a subsidiary beam having a polarized light component perpendicular to the polarized light component of the primary beam and a double-humped pattern, in which the center position coincides with the center position of the primary beam and the principal portion is equal in size to the principal portion of the primary beam. The primary beam and the subsidiary beam are focused onto an information storage surface of an optical disk and reflected therefrom, so that they are separated again through polarization separation and individually detected by first to third optical detectors. The output signals from the first to third optical detectors are calculated by a differential calculator and outputted therefrom.

摘要： A linearly polarized light beam emitted from a first coherent light source is focused, as a primary beam, onto a preparation via an objective lens. A subsidiary beam emitted from a second coherent light source is a linearly polarized light beam having a plane of polarization perpendicular to that of the primary beam. The subsidiary beam is focused onto the above preparation as a double-humped beam having a center in the same position as that of the primary beam. The principal portion of the subsidiary beam is equal in size to that of the primary beam. The preparation is scanned with the two beams being superimposed on each other. After transmitted by the preparation, the two beams are separated into the primary beam and the subsidiary beam again upon passing through a second polarizing beam splitter so that they are detected individually by first and second optical detectors. Output signals from the first and second optical detectors are calculated by a differential calculator and displayed on a display unit via a second control means.

摘要： A holographic optical information recording/reproducing device is provided with a laser light source 1 and a polarizing beam splitter 8 for splitting a light from the laser light source 1. At the time of recording information, one of light beams split by the polarizing beam splitter 8 is modulated by a spatial light modulating element 2 to form a beam array, which becomes a signal light 25, whereas the other split light beam becomes a reference light 22. Interference fringes generated by the signal light 25 and the reference light 22 are recorded as holograms in a holographic disc 5. At the time of reproducing the information, only the reference light 22 is irradiated to the holographic disc 5 and its diffracted light is detected. At this time, the holographic optical information recording/reproducing device makes the power of the reference light 22 in the holographic disc 5 for information reproduction larger than a sum of the power of the reference light 22 and the power of the signal light 25 in the holographic disc 5 for information recording.
