Turning optical imaging system

The invention provides a turning optical imaging system for solving the technical problem that in the background art, a coaxial optical imaging system can not be used for obtaining high-definition images after an optical path is turned. The turning optical imaging system comprises a lens cone A, a lens cone B and a camera, wherein an aperture is arranged in the lens cone B; the lens cone A is directly connected with the camera by a camera lens holder, one end of the lens B points to a shot object, and the inside of the other end of the lens cone B is provided with an isosceles triangle prism for turning an optical path; and the lens cone A is fixedly connected with the lens cone B along the axial direction of the lens cone A by a rotating slip ring by which the lens cone B rotates around the central shaft of the lens cone A. By using the bending optical imaging system provided by the invention, the imaging of an object at a special angle position can be realized; the turning optical imaging system has the cha
