摘要： The invention relates to a method of illuminating at least two illumination points by means of at least one spatial light modulator, said at least one spatial light modulator comprising a plurality of light modulators, whereby a predefined amount of energy transmitted to said points is at least partly controlled by varying the number of said light modulators illuminating said point. According to the invention, an advantageous way of transmitting optical energy to an illumination point has been obtained.

摘要： An apparatus and method of printing images onto a photosensitive media (140) using multiple reflective spatial light modulators (87, 88, 89, 90, 95, 97). In the apparatus and method, illumination optics uniformize and image light from at least one light source (20) through polarization beamsplitting elements (60, 63). The polarization beamsplitting elements (60, 63) divide the illumination light into two polarization states. One polarization state of the illumination light illuminates the reflective spatial light modulators (87, 88, 89, 90, 95, 97) in a telecentric manner. The reflective spatial light modulators (87, 88, 89, 90, 95, 97) are addressed with image data signals. The reflective spatial light modulators (87, 88, 89, 90, 95, 97) modulate the polarized illumination light on a site by site basis and reflect the modulated light back through the polarization beamsplitting elements. The modulated light beams are combined to form an image, which is directed through a print lens assembly (110) to expose a photosensitive media (140). The position of the spatial light modulators (87, 88, 89, 90, 95, 97) can be changed, and a new image can be printed.

摘要： The transfer apparatus includes a light source, a transmission type image display device in which a liquid crystal layer is held between two sets of substrates and polarizing plates and a photosensitive recording medium. The light source, the image display device and the photosensitive recording medium are arranged in series along a direction in which light from the light source advances and the image display device and the photosensitive recording medium are arranged in a non-contact state. A display image transmitted from the transmission type image display device is transferred to the photosensitive recording medium. A distance between the image display device and the photosensitive recording medium and a sum total of thicknesses of the substrate and the polarizing plate at least on a side of the photosensitive recording medium in the image display device are set in accordance with a definition of the display image.

摘要： An optical printer which exposes photosensitive paper (500) at a preset timing using light from a light source (110) moving relatively to the photosensitive paper (500) and based on image data comprising pixels having a plurality of gradations which linearly vary from a low-color-density minimum gradation to a high-color-density maximum gradation, wherein an area gradation is effected by adjusting an exposure distance to form a gradated image on the photosensitive paper (500). A gradation does not change in proportion to an exposure distance over a whole range but changes non-linearly.
