專利摘要：
A field-of-view switching and focusing system of a common-optical-path periscope, having an aspherical reflecting mirror system, a field-of-view driving system and a focus driving system. The field-of-view driving system and the focus driving system are located at two sides of the aspherical reflecting mirror system. The field-of-view driving system allows the aspherical reflecting mirror system to rotate, thereby, different curved faces of the aspherical reflecting mirror can reflect the incident light, so that the field of view can be switched. Further, by a linear movement of the aspherical reflecting mirror system driven along the optical path by the focus driving system, the focus fine adjustment is performed.
