Abstract
Abstract An infrared simulator serves to directly transduce electron beams into infrared radiation. To this purpose a modified cathode-ray tube is provided which includes an infrared transmissive window. Behind this window a film within the vacuum of the cathode-ray tube is arranged in order to transduce the electron bombardment into infrared radiation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
37 words
Infrared simulator comprising an evacuated cathode-ray tube having a window transmissive to infrared radiation and a film behind the window and within the vacuum of the cathode-ray tube, said film primarily transducing electron bombardment into infrared radiation.
Claim 2
Dependent Claim
37 words
Infrared simulator comprising an evacuated cathode-ray tube having a window transmissive to infrared radiation and a film behind the window and within the vacuum of the cathode-ray tube, said film primarily transducing electron bombardment into infrared radiation.
Claim 3
Dependent Claim
32 words
Infrared simulator according to claim 1, in which the film forms the screen of a cooled cathode-ray tube and the cathode-ray tube is inserted in an evacuated housing closed by said window.
Claim 4
Dependent Claim
39 words
Infrared simulator according to claim 1 or 2, in which the bulb of the cathode-ray tube as well as the suspension of the film are connected to a cooling circuit in order to improve temperature dynamics of said film.
Claim 5
Dependent Claim
30 words
Infrared simulator according to one of claims 1 or 2 characterized in that the window at the same time forms an adaptation optics for an infrared sensor to be tested.
Claim 6
Dependent Claim
52 words
Infrared simulator according to one of claims 1 or 2, characterized by a process control computer with a data memory to modulate the intensity and to deflect the electron beam of the cathode-ray tube and to evaluate the infrared image signals delivered from an interrface to which the infrared sensor is connected.
