ABSTRACT:
A shutter is designed for use with an optic fibre which is designed to emit rays in a cone in a selected viewing direction. A mount carries the optic fibre to emit such cone. Associated with the mount is structure for rotatably mounting the shutter, or rotor to rotate between ON and OFF positions. The shutter is shaped to provide a panel which blocks the cone in the viewing direction in the OFF position. The shutter is shaped to define, in an ON position, a central opening for passage of the cone of light in the viewing direction. Rotation between the ON and OFF positions is about 90.degree.. An Electromagnetic drive is used to drive the shutter between the ON and OFF positions. The fibre is centrally located relative to the fibre mount. A plurality of shutters, each with its own drive may be arranged in line, in a single strip module.
