Abstract

We discuss the strategy of search for fast optical transients accompanying gamma-ray bursts by means of continuous monitoring of wide sky fields with high temporal resolution. We describe the design, performance and results of our cameras, FAVOR and TORTORA. Also we discuss the perspectives of this strategy and possible design of next generation equipment for wide-field monitoring which will be able to detect optical transients and to study their color and polarization properties with high time resolution.
