    • Method for producing a large size mirror from a thin film, involving (a) the attachment of a thin film to a suction chamber, the edge of which has the required geometry of the mirror, and (b) the production of a controllable partial vacuum in the suction chamber so that the thin film takes on the required geometry of the mirror. The method is characterized in that the region of the mirror having the required geometry is enlarged by preshaping the thin film, prior to the attachment thereof to the suction chamber, by controlled tensioning in a closed pressurization chamber comprising two circular discs with a common axis and a thin film which is attached to the edges of the discs and the lateral sides of which are conjoined so as to form a conical surface, and by additionally tensioning the thin film by means of a mechanism for moving the discs apart along the common axis thereof. In order to facilitate and accelerate the process of forming a mirror from a thin film, the pressurization chamber together with the thin film attached thereto is placed in a thermal box in which the film is uniformly heated to an optimum temperature for deforming the film under increased pressure in the pressurization chamber.
    • 用于从薄膜制造大尺寸反射镜的方法,包括(a)将薄膜附着到吸入室,其边缘具有反射镜所需的几何形状,和(b)产生可控的部分真空 在吸入室中,使得薄膜具有所需的几何形状的反射镜。 该方法的特征在于,具有所需几何形状的反射镜区域通过在其附着到吸入室之前通过预先形成薄膜而被扩大,通过在具有公共轴线的两个圆盘的封闭加压室中受控张紧,并且 连接到盘的边缘并且其侧面结合以形成圆锥形表面的薄膜,并且通过用于沿着其公共轴线分离盘的机构附加地张紧薄膜 。 为了促进和加速从薄膜形成反射镜的过程,将加压室与附着在其上的薄膜一起放置在热箱中,其中将膜均匀地加热至最佳温度,以使薄膜在增加的情况下变形 加压室内的压力。

    • A method of reproducing a three dimensional (3D) image by counter-distorting a two dimensional (2D) image prior to vacuum forming. A captured or obtained image of a subject is digitalized into 3D and 2D formats and used to create a 3D surface using a CNC machine. A standardized grid pattern with numerous reference points is printed on a vacuum formable material and vacuum formed on the 3D surface representing a subject. The reference points on the grid are displaced during the vacuum forming process due to the 3D nature of the surface. If the image of the subject were printed on the vacuum formable material, it would appear distorted. The displaced reference points are observed and the data is entered into the inventive software which generates a new image with compensated morphological changes. When the new image is vacuum formed on vacuum formable material under the same conditions, the new image would not appear distorted and would accurately depict the subject in 3D.
    • 一种通过在真空成形之前对二维(2D)图像进行逆变形来再现三维(3D)图像的方法。 拍摄或获得的被摄体图像被数字化为3D和2D格式,并用于使用CNC机器创建3D表面。 具有许多参考点的标准网格图案印刷在真空成形材料上并形成在表示被摄体的3D表面上的真空。 由于表面的3D特性,真空成型过程中网格上的参考点被移位。 如果被摄体的图像印在真空成型材料上,则会出现扭曲。 观察到偏移的参考点,并将数据输入到本发明的软件中,该软件产生具有补偿形态变化的新图像。 当在相同条件下在真空成型材料上真空形成新图像时,新图像将不会出现扭曲,并能精确地描绘3D中的对象。
