    Abstract: 1. In combination with a moving vehicle a line scanning apparatus secured to the vehicle comprising a main imaging lens to image the subject upon a focal plane, a thin flexible fiber optic unit of sheet-like form having its fibers arranged in the same lateral sequence at its input and output ends and operable to transmit one scan line at a time from said focal plane to an arcuate line at its output end, a driven scanner rotating upon an axis at the center of said arcuate line having at least one scanning lens of short focal length fixed on the scanner to move close to the said arcuate end of the fiber optic unit in focus with the ends of the fibers, means to produce timing signals at the beginning and end of each line scanned, a fixed condenser lens, a mirror fixed to the scanner positioned to reflect light passing through the scanner lens to said condensing lens, a fixed aperture plate acting to reduce the reflected light passing the condenser lens to a small area beam, light sensing means receiving said small beam and communication and reproduction means modulated by the output of said sensing means.

    Abstract: An electro-optical indoor training device which permits operators of one or more laser carrying weapons to aim at a realistic simulated target scene presented by a motion picture film projector. Each frame of the film contains a first portion representing a scene including at least one target area at which the laser beam of any given weapon should be directed and a second portion which is substantially opaque to laser radiation except for a transparent region thereof corresponding in location exactly to the location of the target area in the first portion of the film frame. Each weapon has a low power laser attached thereto which can be excited by actuating the weapon trigger and by automatic electronic delay, thereby firing the laser at previously determined time intervals; the laser beam, if properly aimed at preselected areas of the target scene on the projection screen, will be focused onto hit detection means, whereas an improperly aimed laser beam will impinge upon attempt detection means. Attempts and hits for all involved weapons are scored on an individual basis by electronic display means and electronic multiplexing means (when more than one weapon is to be fired) for synchronizing non-concurrent firing of the various weapons with film frame projection.

    Abstract translation: 一种电光室内训练装置，其允许一个或多个激光携带武器的操作者瞄准由电影胶片投影仪呈现的现实的模拟目标场景。 胶片的每个框架包含表示场景的第一部分，该场景包括至少一个目标区域，在该区域内应该引导任何给定武器的激光束，而对于激光辐射基本上不透明的第二部分，除了位置对应的透明区域 恰好相对于胶片框架的第一部分中的目标区域的位置。 每个武器具有附接到其上的低功率激光器，其可以通过致动武器触发器和通过自动电子延迟来激励，从而以预先确定的时间间隔发射激光; 如果适当地瞄准投影屏幕上的目标场景的预选区域，激光束将被聚焦到命中检测装置上，而不正确瞄准的激光束将撞击到尝试检测装置。 所有相关武器的尝试和命中都是通过电子显示装置和电子复用手段（当多于一种武器被射击时）以个别方式进行打分，用于同步不同武器与电影框架投影的非同时发射。
