METHOD OF MEASURING RADIATION SPECTRUM, SPECTROMETER AND SMALL- SIZED SPECTROMETER Russian patent published in 2005 - IPC

FIELD: spectrometry.

SUBSTANCE: method and devices provide preliminary division of tested radiation flow to two parts which are sent to diffracting screen separately through two slits shifted one relatively the other at the direction being perpendicular to plane of Rowland's circle. Then parts of flow are sent to different linear video signal linear formers. At one linear video signal former the part of spectrum is formed from one part of flow which has to be continuous prolongation of part of spectrum formed at the other linear video pulse former from the other part of flow.

EFFECT: eliminated loss of useful data; improved precision of measurement.
