3 Strategy for GRB searches in optical range

(1) it is feasible to use ground based optical devices to monitor OAs of GRBs (2) these surveys must be of wide field and high sensitivity (3) these surveys will suffer by high rate of background triggers (4) the recent SNe searches may be used to detect OAs (5) the rates of most background triggers are poorly investigated so far (6) the detected OTs must be further studied to eliminate them from background triggers.

Numerous space and ground-based experiments can be used for these purposes such as the OMC (Optical Monitoring Camera) onboard INTEGRAL ($5 \times 5$ deg², lim mag 19), CCD-based devices and telescopes (ASPA, OTM, BOOTES), digitized plate surveys and digitized archival plates.
