A bichromatic imaging method in solar studies

Radiophysics and Quantum Electronics Aims and scope

Abstract

The basic concept of a bichromatic imaging technique has been formulated. Specific applications of this method are analyzed in the context of the examination of solar plasma characteristics by pinpointing its merits and demerits. Specialized requirements for the spectral devices are set forth, which can be summarized as: a) the presence of two nearby identical spectral passbands, b) the mutual orthogonality for the polarization of the light transmitted through the neighboring bands, and c) the possibility of controlling the relative position of the bands. Several alternative plausible implementations of the method are considered, using Fabry-Perot interferometers (FPI) and magnetooptical filters (MOF) to measure the longitudinal magnetic field strength and the intensity field. A new MOF-based design of a filter magnetograph is proposed, in which two optical resonance cells are combined into one.
