The modernization of the instruments and software complex of the MANIA
experiment for searching for and studying the variability of astrophysical
objects with a temporal resolution of 10-6s has been completed.
The designed observation complex, having no analogues in the world, provides
the possibility of registering photon fluxes from optical sources with
a microsecond temporal resolution and determining their energy and
polarization characteristics. As radiation receivers, two position-sensitive
detectors are used with sensitivity maxima in the long- and short-wave
regions of the spectrum (V. Debur et al., NIM in Physics Research,
2003, A 513, 127., V.L. Plokhotnichenko et al., AB SAO, 2020,
75. 1. pp.65-75) with the determination of the registration moments of
quanta by the chronometric "Quantochron 4-48" instruments
(V.L. Plokhotnichenko et al., AB SAO. 2009, 64, 2, pp.204-210) and the
EMCCD camera. The operating modes provided by the complex with the
measurement of 3 Stokes parameters are: 1 - the broadband mode,
2 - the high-sensitivity mode with an EMCCD camera, 3 - the
UBVR photometric mode, 4 - the spectral mode with an Abbe prism,
5 - the spectral mode with a diffraction grating, see the figure.
They are changed remotely in 1-5 minutes, and the registration, storage,
and reduction of data are provided by an information cluster consisting
of 7 computers, which makes it possible to continuously
register photon fluxes and their coordinates measured on detectors
throughout the night with an accuracy of reference to UT of 0.1 ms.
The results obtained from observations of X ray sources, flare stars,
and optical pulsars demonstrate the effectiveness of using the designed
complex in high-resolution astronomy and relativistic astrophysics.
