采用共轴理论和控制离焦相结合的方法，设计了大画幅等待式转镜分幅相机，该相机的画幅尺寸达到了30 mm×18 mm，同时还具备了相对孔径大和分辨率高的特点，对底片的相对孔径为空间方向1/15和扫描方向1/35，动态目视分辨率达到了35 lp/mm，总画幅数80幅，摄影频率1×104～5×105 frame/s。采用2×105 frame/s的拍摄频率对某爆轰过程进行了试验记录，得到了高分辨率的图像。结果表明：相机的画幅尺寸大、空间分辨率高，适用于冲击、爆轰和弹体姿态等试验过程和目标的拍摄。

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.
