<p>An optical module is disclosed which can effectively observe an event or object. The optical module includes: a first mirror with a wide field of view (FOV), for detecting the event or object over a wide area of observation; a second mirror including a plurality of mirror cells each of whose focal length is greater than that of the first mirror, in which the plurality of mirror cells control the wide area of observation detected by the first mirror, correspondingly and respectively, so that one of the mirror cells corresponding to a particular position of the wide area of observation can observe, at a high resolution, the event or object in the wide area of observation detected by the first mirror; an optical signal detector for detecting an optical signal transmitted from the first mirror or the second mirror; a body including the first mirror, the second mirror, and the optical signal detector therein, and forming apertures which correspond to the first mirror and the second mirror, respectively, the body providing an optical path from the first mirror or the second mirror to the optical signal detector; and a controller for determining whether the detected event or object is a target of observation, for reading a position of the detected event or object when concluding that the detected event or object is a target of observation, and for controlling the first mirror and the second mirrors. The controller provides an optical path to only one of the mirror cells of the second mirror, which corresponds to the particular position of the event or object detected by the first mirror, and to block optical paths to the remaining mirror cells. The optical module is configured to include: a first mirror having a wide FOV, for detecting the event or object over a wide area of observation; and a second mirror including a plurality of mirror cells each of whose focal length is greater than that of the first mirror, in which the plurality of mirror cells control the wide area of observation detected by the first mirror, correspondingly and respectively, so that one of the mirror cells corresponding to a particular position of the wide are of observation can observe, at a high resolution, the event or object in the wide area of observation detected by the first mirror.</p> |
