spherical shutter

In order to meet the demand for a film-space camera with large aperture to take photograph,a type of focal plane-curtain shutter is designed,which utilizes the movement of front-curtain and back-curtain to form a narrow slit, and then makes the film exposure.

为满足胶片型空间相机对地摄影的需要,设计了焦面帘幕式快门,利用快门前、后2层帘布在运动过程中形成的狭缝使胶片曝光。
