We describe the final stage of developing the hardware and software complex of the MANIA experiment (Multichannel Analysis of Nanosecond Intensity Alterations) to search and study the brightness variations of astrophysical objects with extremely high temporal resolution. The main instrument of the complex is a panoramic photospectropolarimeter with remotely mounted optical blocks that feed light beams to the photo-receiving devices (PRD) with position-sensitive detectors (PSD), the individual quanta of which are registered by chronometric devices with a 30 ns cadence and with each quantum linked to universal time. We present some scientific results obtained through observations with the 6-meter telescope of SAO RAS, as well as plans of further hardware development and its application.

It was supported by INTAS (grant No. 04-78-7366), RFBR (grant No. 04-02-17555), and the support fund for scientific pro- grams of the Presidium of the Russian Academy of Sciences. Observations with SAO RAS telescopes are supported by the Ministry of Science and Higher Education of the Russian Federation No. 075-15-2022-262 (13.MNPMU.21.0003) and the Federal Program for Increasing the Competitiveness of Kazan (Volga Region) Federal University.
