Optical Module for Observing Event or Object

Abstract

An optical module that effectively observes a rapidly moving event or object is provided. The optical module includes first and second mirrors, and an optical signals detector, which are installed in a body thereof. The first mirror has a wide field of view and detects the event or object over a wide observing region. The second mirror observes the event or object detected by the first mirror at a high resolution. The focal length of the second mirror is greater than that of the first mirror. The optical signal detector detects an optical signal in light transmitted from the first mirror or the second mirror. The body forms apertures which correspond to the first and second mirrors, respectively and provides an optical path from the first and second mirrors to the optical signal detector. Therefore, the optical module can observe the event or object detected by the first mirror at a high resolution.
