Focal-plane Shutter - Electro-optical Shutters

Electro-optical Shutters

Instead of using relatively slow-moving mechanical shutter curtains, electro-optic devices such as Pockels cells can be employed as shutters. While not commonly used, they completely avoid the problems associated with travelling-curtain shutters such as flash synchronisation limitations and image distortions when the object is moving. Such shutters are significantly more costly than mechanical shutters.
