Title: Electro-optical converters
Inventor: HOWORTH JONATHAN ROSS
IPC: H04N9/04
Filed: 1981-10-07
Abstract: An electro-optical converter is arranged to retain the colour content of a very low intensity optical image and may form part of a low light television camera. The converter includes an image intensifier (9) having an input formed as a colour filter (2) having blue, green and red elements (3, 4, 5). The different colours of the incident image are greatly intensified by the image intensifier and its output is fed to a solid state optical sensor such as charge coupled device (12). The output of the device constitutes a video signal representative of the viewed scene, and its colour content can be extracted from a knowledge of which elements of the charge coupled device receive illumination from the filter elements of the different colours. The image intensifier is preferably a micro channel plate amplifier having electron multiplying channels. The filter may be formed as a fibre-optic plate (7) which prevents image spreading and crosstalk, and a further fibre optic plate (11) may be provided between the image intensifier and CCD array. <IMAGE>
