METHOD OF MODULATION OF RADIATION INTENSITY AND DEVICE FOR ITS REALIZATION Russian patent published in 2001 - IPC

FIELD: spectral instrumentation. SUBSTANCE: invention is intended to generate radiation spectra with modulation by exposure according to certain law. Salient feature of invention lies in motion of working edge of aperture diaphragm about axis of rotation of electromechanical rotary gear whose time dependence of rotation law is set analytically to provide for certain ( harmonic, linear, etc ) law of modulation of intensity of dispersed radiation across output of spectral device. EFFECT: improved functional reliability of method and device. 2 cl, 5 dwg
