    • A stereolithography apparatus that is configured to fabricate a three-dimensional model by forming a cured layer by irradiating an interface of a photocurable resin with light corresponding to sectional data of the three-dimensional model and stacking the cured layers includes a container holding the photocurable resin and having a constraining window configured to constrain the interface of the photocurable resin; a vertical movement table movable in a vertical direction orthogonal to the interface of the photocurable resin; an optical system configured to form the cured layer between the vertical movement table and the constraining window by irradiating the interface of the photocurable resin with light through the constraining window; and a position constraining mechanism configured to substantially flatten the constraining window by applying a force to the constraining window from the outside of the container when the cured layer is formed by the optical system.

    • There is provided an optical modeling apparatus that forms a model of a desired shape by sequentially forming hardened layers by irradiating a light-curable resin with light. The apparatus includes a first light source that emits a light beam for plotting on the resin, a scanning device that scans the light beam from the first light source over the resin, a second light source that emits light that irradiates one fixed region of the resin at a time, and a spatial light modulator that spatially modulates the light from the second light source to blanket-expose a specified region of the resin. The light beam from the scanning device and the light from the spatial light modulator form each hardened layer.
    • 提供了一种通过用光照射光固化树脂依次形成硬化层来形成所需形状的模型的光学建模装置(1)。 该装置包括:发射用于在树脂上绘制的光束的第一光源(11);扫描装置(21,22),用于扫描来自第一光源的光束穿过树脂,第二光源(31) 一次发射树脂的一个固定区域的光,以及空间光调制器(32),其对来自第二光源(33)的光进行空间调制,以覆盖树脂的特定区域。 来自扫描装置(21,22)的光束和来自空间光调制器(32)的光形成每个硬化层。

    • A single photographic subsystem (2) photographs an original image for a hologram and provides an image information file (Fp). In addition, this subsystem provides a management information file (Fm) for storing management information about the image information file (Fp). An image processing section (4) generates a composite image file (Fs) by applying specified image processing to the image information file (Fp) and the management information about the management information file (Fm) provided from the single photographic subsystem (2) via a transmission system (3a). A hologram printer (5) receives the composite image file (Fs) generated in the image processing section (4) and prints a holographic stereogram based on this composite image file (Fs).
    • 单个摄影子系统(2)拍摄全息图的原始图像,并提供图像信息文件(Fp)。 此外,该子系统提供用于存储关于图像信息文件(Fp)的管理信息的管理信息文件(Fm)。 图像处理部(4)通过对图像信息文件(Fp)应用指定的图像处理和从单张照相子系统(2)提供的关于管理信息文件(Fm)的管理信息经由 传输系统(3a)。 全息打印机(5)接收在图像处理部分(4)中生成的合成图像文件(Fs),并且基于该合成图像文件(Fs)打印全息立体图像。
