摘要
FIELD: optical spectrometry, spectral analysis of objects. SUBSTANCE: input mask letting radiation pass through it is employed for analysis of spectra of radiation source without procedure of scanning of source surface. Its autocorrelation signal has high degree of localization and is used as resolution element. Since Information on input mask is recorded on holographic filter. While such filter is illuminated by radiation of extended source passed through mask signal comprising localized autocorrelated signals of input mask will be formed on each length of waves included in radiation spectrum of source. This signal will present picture of spectral composition of source. EFFECT: generation of spectral composition of extended radiation source without scanning procedure. 4 dwg
