摘要	In this study, a novel type of lens shutter with compact structure, reasonable layout and high reliability was designed for use in digital aerial photography mapping cameras. The double-blade shutter achieved the same shutter efficiency as a five-blade shutter. A coaxial gear train with different transmission ratios drives the double-blade rotation by miniaturized design, thereby controlling exposure. The speed of the blade is varied continuously by controlling motor speed, which helps attain the appropriate exposure. Simulation and experimental analysis of the shutter indicates that the range of shutter exposure time reaches 1/100 s-1/1000 s, and the shutter efficiency can increase to 85%. The shutter with wide exposure time and high shutter efficiency is found to have small effects on optical distortion, and sufficient stiffness to meet the camera requirements. 2018, Science Press.
