    • A scanning optical system for incrementally generating a composite image of a strip-scanned object. A light beam (12) is swept by a first rotating mirror (17) across the object (21) to scan-illuminate the same. Imaging light from the object is then projected to an intermediate image station across which it is swept by a second rotating mirror (23). A stationary aperture (S2) at the intermediate image station transmits or reflects, at any instant, only a desired incremental image of the scanned object. This desired incremental image is in turn relayed to a final image plane by reflection from a third rotating minor (28) so as to synchronously lay down on the image plane a composite of the instantaneous increments.
    • 一种扫描光学系统,用于递增地生成条带扫描对象的合成图像。 光束(12)被穿过物体(21)的第一旋转镜(17)扫过,以对其进行扫描照明。 然后将来自物体的成像光投射到中间图像站,在该中间图像站中,被第二旋转镜(23)扫描。 在中间图像站处的固定孔径(S2)在任何时刻发射或反射仅扫描对象的期望的增量图像。 通过来自第三旋转次要装置(28)的反射将该期望的增量图像又传递到最终图像平面,以便同步地在图像平面上放置瞬时增量的复合。

    • An afocal apparatus for the optical-mechanical scanning of an object in two dimensions includes a collimation objective (O), a first scanning means (1) for scanning the object in a first dimension via the objective (O), a second scanning means (2) for scanning the object in a second dimension, intermediate optics (M) between the first and the second scanning means, a detector (D) and a relay optical system (OR) between the detector (D) and the second scanning means (2). The intermediate optics is formed by a primary mirror (12) and a secondary mirror (11) which are substantially concentric and face-to-face with a substantially common centre (3) of curvature and a mutual spacing sustantially corresponding to the radius of curvature of the secondary mirror. A pupil position (P') can be arranged at one of the scannig means, the other scanning means being situated at a conjugate point (P'') to the pupil position in relation to the intermediate optics (M). The width ( DELTA ) of the secondary mirror (11) is adjusted to the width of the detector image (D) so that the longitudinal edges of the secondary mirror (11) constitute a field line aperture (F). The bundles of rays incident on, and coming from the intermediate optics can be limited and situated as close to the secondary mirror as posible. The primary mirror can be parted in the symmetrical plane of the optics, the mirror halves being outwardly turned a small angle. The mirrors of the intermediate optics may consist of ellipsoid cutouts. Of the possible combinations of ellipsoid cutouts, there are some which are significantly better than the others.
    • 用于物体在两个维度上的光学机械扫描的无焦点装置包括准直物镜(O),用于经由物镜(O)在第一维中扫描物体的第一扫描装置(1),第二扫描装置 2)用于在第二维度扫描物体,第一和第二扫描装置之间的中间光学器件(M),检测器(D)和检测器(D)和第二扫描装置(D)之间的中继光学系统(OR) 2)。 中间光学元件由初级反射镜(12)和次级反射镜(11)形成,它们基本上同心并且面对面地具有基本共同的曲率中心(3)和相对于曲率半径的相互间隔 的次镜。 瞳孔位置(P')可以布置在扫描装置中的一个上,另一扫描装置位于与中间光学元件(M)相对于光瞳位置的共轭点(P“)处。 将副反射镜(11)的宽度(DELTA)调整为检测器图像(D)的宽度,使得副反射镜(11)的纵向边缘构成场线光圈(F)。 入射到中间光学器件上并且来自中间光学器件的光束可以被限制并且被定位成靠近次级反射镜。 主镜可以分离在光学器件的对称平面中,镜面半部向外转一个小角度。 中间光学镜的反射镜可以由椭圆形切口组成。 在椭圆形切口的可能组合中,有一些明显优于其他切口。
