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.

Famous quotes containing the word shutters:
“The wind attendant on the solstices
Blows on the shutters of the metropoles,
Stirring no poet in his sleep, and tolls
The trand ideas of the villages.
The malady of the quotidian. . . .”
—Wallace Stevens (1879–1955)
