METHOD OF SPECTROMETRY AND INTERFEROMETER FOR REALIZATION OF THIS METHOD Russian patent published in 2002 - IPC

FIELD: spectral analysis. SUBSTANCE: system of interference bands of standing light wave is recorded in form of signal of spatial frequency through imaging the said system on periodic system containing photocells whose signals are recorded in form of dependence of position of these photocells in said periodic system and are subjected to analysis. Proposed method is realized with the aid of interferometer containing the following optically engageable components: light radiation source, reflecting mirror, spectroanalyzer and thin partiallytransmitting light- sensitive layer located in inclined position between light radiation source and reflecting mirror partially transmitting light radiation. Interferrometer is also provided with optically engageable periodic system containing photocells; this system is located behind reflecting mirror. EFFECT: enhanced accuracy of measurement of light waves by 2 to 5 times at measurement of light radiation of wide spectral band. 5 cl, 2 dwg
