Abstract

In this paper we consider the possibility of modulationless measuring the magnetic-field strength and the differential line-of-sight velocity, based on using a diffraction spectrograph and multichannel CCD photodetectors. The optical system for implementing the method is described. Results of trial observations are presented. When measuring the differential velocity, the spectrograph’s inherent noise is reduced by factors of 35–40. It becomes possible to measure the longitudinal magnetic-field strength in a single exposure even if the CCD array is used. This can be particularly attractive when reducing the influence of atmospheric instabilities on the result of magnetic-field measurement using CCD arrays.
