DEVICE FOR INDICATION AND VISUAL OBSERVATION OF IR-RANGE ELECTROMAGNETIC RADIATION Russian patent published in 1994 - IPC

FIELD: electro-optics. SUBSTANCE: photometric sphere is used as thermostating dish. Radiation to be indicated is incident onto the luminescent screen through the modulator and hole in photometric sphere. The screen is uniformly illuminated with source UV-radiation, being incident on wall of photometric sphere. Screen is illuminated with indicated radiation and UV-radiation at different periods of time due to application of two modulators with constant phase difference. Windows, provided with light filters are used for visual observing and photoelectric indication; the windows are transparent to radiation of luminescence of the screen only. When indicating super high frequency fields, the sphere and the coating, which dissipates radiation diffusively, are made of material being transparent to superhigh frequency oscillations. EFFECT: improved precision. 2 cl, 1 dwg
