摘要： An optical mixer for use in a helmet visual display system including a light intensifier tube for night vision and a cathode-ray tube for the display of a synthetic image. The mixer includes a swinging glass plate with a spectrally reflective and angularly selective coating. When the angle of the swinging glass plate is changed, the amount of light transmitted through the mixer is changed.

摘要： The device finds application, particularly, in the instrument panels of aircraft, where it comprises: three liquid crystal optical valves, controlled by three electrical signals respectively representing a red image, a green image and a blue image. Two holographic mirrors are utilized, as is a standard mirror and two dichroic strips to illuminate the three valves respectively by three beams, colored red, green and blue, from a single source of white light, while at the same time reducing the space occupied by the optical elements needed to guide the three beams to the minimum. A dichroic cube then superimposes the three beams coming respectively from the three valves and an optical system to form a trichromatic image on a diffusing screen. The optical system collimates the rays coming from the image formed on the diffusing screen to enable an observer to see an image collimated at long distance, with a wide field.

摘要： The invention relates to planar display screens and more particularly to smectic liquid crystal screens.One of the problems of high definition display screens (approximately 100 to 1000 lines and columns) is caused by the devices for controlling the heating current on the lines. The complexity of the installation and costs limit the increase in the definition. The invention arranges the N lines of a screen into .sqroot.N groups of lines supplied at each of their ends by .sqroot.N control devices functioning sequentially, i.e. 2.sqroot.N devices in all. Moreover, each line has a diode placed between the heating resistor and the common point of the circuit.Application to the display of images transmitted in the form of a video signal for television and display peripheral equipment in teletransmission.
摘要翻译：本发明涉及平面显示屏，更具体地涉及近晶液晶屏。高分辨率显示屏幕（大约100到1000行和列）的问题之一是由用于控制线路上的加热电流的装置引起。安装和成本的复杂性限制了定义的增加。本发明通过顺序运行的2ROOT N个控制装置，即2个2个N个装置，将每个屏幕的N行排列成两端的N组线。此外，每条线路具有放置在加热电阻器和电路的公共点之间的二极管。应用于以电视机的视频信号的形式传输的图像的显示和显示外围设备的传输。
