Abstract
One of the essential difficulties of spectral researchers atmosphere on scattering from ground Solar light is the contradiction between necessity of work with the small angular aperture, its need for satisfactory work of spectral devices, and with necessity of its increase to ensure a sufficient energy level of radiation on an input of photoreceivers. One of the decisions of this problem is installation of the spectral device (for example, Fabry-Perot interferometer) before focusing lens. Unfortunately such decision is connected to technological difficulties of creation of spectral devices with the large linear aperture. In submitted work the given problem is solved with the help of installation before an entrance of the photoreceiver of a mask adjusting phase structure of incident radiation, to ensure inphase addition of under different incident waves on spectrometer. Accounts of structures of such masks for interference-polarization light filter, Fabry-Perot interferometer with flat mirrors and Fabry-Perot interferometer with connected by convex and concave mirrors are resulted. Technological ways of creation of such masks are considered.
