The optical imaging system

The invention relates to an optical imaging system comprising a sensing chip, at least one set of optical lenses and at least one curve reflecting mirror. The optical lenses are arranged in an optical passage in which the sensing chip is located for regulating light rays. The curve reflecting mirror corresponding to the sensing chip is arranged at the other sides of the optical lenses for reflecting the light rays in a light path of the optical imaging system. The optical imaging system can utilize the curve reflecting mirror to reflect the light rays in the optical imaging system, and because the curve reflecting mirror has the property of reflecting light rays in a larger view field range, the optical imaging system can obtain a larger view field angle.
