A large-frame continuous rotating mirror framing camera is developed by using the coaxial imaging theory and controlling defocusing range. It has the frame size of 30 mm×18 mm, dynamic visual resolution of 35 lp/mm, relative aperture of 1/15 in spatial direction and 1/35 in scanning direction, frame number of 80, and framing rate from 1×104 to 5×105 frame/s. The camera runs conveniently under a new control system. High-resolution images about a detonation experiment are obtained with this camera under the framing rate of 2×105 frame/s. It is proved that this camera can be used for imaging in such experiments as shock wave, detonation and gesture of bowb.
