Abstract
A device is divulged for generating an infrared image, in which an electron beam having a section substantially equal to the area of a pixel formed from a material having high emissive power in the infrared, directly bombards this material. The energy of the beam is transformed into heat then into infrared radiation, in the material. Each pixel is supported by a slab of a material transparent to the infrared, which is heat insulating and deposited on a screen transparent to the infrared and heat conducting.
