High Temporal Resolution Multi-Mode Panoramic Photospectropolarimeter

The paper describes a new stage in the development of the hardware-software complex of the MANIA experiment to search for and study the brightness variability of astrophysical objects with a temporal resolution of s. The panoramic photospectropolarimeter uses the remotely mounted optical units—the color separation modules which allow one to carry out observations in five modes: the most transparent, multi-band, photo-polarimetric, spectroscopic, and spectro-polarimetric. Two photodetectors (PDs) based on position sensitive detectors (PSDs) with the S-20 and GaAs cathodes, the multiplication of photocurrents with microchannel plates (MCPs), and detection using collectors with the number of elements from 4 up to 16 and an EMCCD camera allow one to detect light fluxes from objects and reference stars in a field of view of up to in several color bands in the low resolution spectroscopic mode, and at the same time to measure the linear polarization in three Stokes parameters. The detection system accumulates the observed data: the digitized photocount fluxes from both PDs with a temporal resolution of while the EMCCD camera accumulates video sequences with a subsecond resolution simultaneously with the reception of ultraviolet quanta with a microsecond resolution on a single PD. We present some research results obtained in observations with the 6-m SAO RAS telescope.
