    • The invention contemplates image-motion compensation in an aerial camera in which the slot of a focal-plane shutter (11) moves in a direction transverse to the direction of film (6) transport, and in which film transport is parallel to the direction of flight. In order to compensate for the component of image-motion which is dependent on the field angle and which occurs with laterally inclined displacements of the camera, the slotted shutter (11) is coupled with an encoder (17) which in the course of making the exposure reports to a computer (12) the instantaneous field position (x) of the shutter slot. This computer (12) also determines a speed profile (A, B) in the interval between successive exposures the speed profile being derived from ground-clearance altitude h, flight velocity V.sub.F, focal length f, angle of swing .beta.', and a basic function which is dependent on the type of lens. The computer interprets the feed back signal from the encoder (17) against the speed profile to determine a control signal to regulate the film drive (7, 8).The single lens (5) of the camera can be replaced by a multiple-lens configuration (35), with the fields of the individual lenses in lateral overlap or adjacency to produce wide-angle coverage, in which case the single slot of a single focal-plane shutter may scan all the fields of the individual lenses in a single exposure sweep.For the situation in which a lens or lenses must be changed for adaptation to particular requirements, the lens mounts are coded with lens data, and a code reader (41) coupled to the lens mount provides input data to the computer for selection of the corresponding basic function stored in the computer for the calculation of the speed profile (A, B).

    • An optical system for cameras and projectors includes a reflective convex mirror for a wide-angle view, for example, a sector of one fourth of a sphere to obtain a view of 180.degree.. The optical system further includes a front face reflecting mirror to change the optical path 90.degree., a first focusing lens, a fiber optic bundle and a second focusing lens. The fiber optic bundle has one face in the form of an annulus or sector of an annulus and the opposite face of rectangular shape so that an annular shaped image may be converted into a non-distorted image of rectangular form.
    • 用于照相机和投影仪的光学系统包括用于广角视图的反射式凸面镜，例如球形四分之一的扇形，以获得180度的视野。 该光学系统还包括：用于改变光路90°的前面反射镜，第一聚焦透镜，光纤束和第二聚焦透镜。 光纤束具有环形或环状部分形式的一个表面和矩形形状的相对面，使得环形图像可以转换为矩形形状的非失真图像。

    • A wide angle strip camera system which, in combination, includes a wide angle lens, having a curved conjugate focal surface, a first image-receiving surface, a first curved exposure slit disposed adjacent the first image-receiving surface; the lens, first image-receiving surface and first exposure slit being so mounted that a first curved strip at a constant preselected field angle in an object field is focused on the first image-receiving surface; a second image-receiving surface; a second curved exposure slit disposed adjacent the second image-receiving surface; fold flat elements interposed between the lens and the second exposure slit; the lens, fold flat elements, second image-receiving surface, and second exposure slit being so mounted that a second curved strip at a second constant preselected field angle in the object field is focused on the second image-receiving surface. The system is fixedly supported in a vehicle, such as an aircraft, whereby the forward velocity of the vehicle provides image motion. The exposure slits are curved to correspond to field points of equal range, respectively, so that there is negligible differential image motion within the slits, the slits being of such width in the direction of vehicle motion as to result in uniform exposure; and the image-receiving surfaces are driven in the direction of vehicle movement at speeds corresponding to the altitude-velocity ratio of the vehicle with respect to the object field.
    • 一种广角带相机系统，其组合包括具有弯曲共轭焦面的广角镜头，第一图像接收表面，邻近第一图像接收表面设置的第一弯曲曝光狭缝; 透镜，第一图像接收表面和第一曝光狭缝被安装成使得在物场中具有恒定的预选场角的第一弯曲条被聚焦在第一图像接收表面上; 第二图像接收表面; 设置在第二图像接收表面附近的第二弯曲曝光狭缝; 折叠的平坦元件插入在透镜和第二曝光狭缝之间; 透镜，折叠平坦元件，第二图像接收表面和第二曝光狭缝被安装成使得在物场中具有第二恒定预选场角的第二弯曲条被聚焦在第二图像接收表面上。 该系统固定地支撑在诸如飞行器的车辆中，由此车辆的前进速度提供图像运动。 曝光狭缝分别弯曲以对应于相等范围的场点，使得狭缝内的差分图像运动可忽略不计，狭缝在车辆运动方向上具有这样的宽度，导致曝光均匀; 并且图像接收表面以对应于车辆相对于物场的高度 - 速度比的速度在车辆移动方向上被驱动。

    • Motion picture apparatus is disclosed herein having a light source supplying light to a collective end of a plurality of light wave carrier bundles. A film carrying a plurality of images per frame is interposed between the light source and the light wave carrying bundles so the images are conducted to the opposite or terminal ends of the carriers for application to a segmented or curved screen surface via a lens system. The respective light wave carrier ends are mounted on dynamic scanning plates so that synchronous movement of the carrier ends is produced for improved picture resolution during picture taking and picture viewing.
