摘要： An optical shutter apparatus has a baseplate that defines an aperture in a plane and that has at least first and second tabs that extend outward from the plane. At least a first linear actuator is coupled to the first tab and drives a magnetic shaft between the first and second tabs according to an electrical signal. A shutter blade is coupled to the magnetic shaft and is linearly translatable along a translation path in the direction of the plane between a first and a second position, wherein the shutter blade blocks at least a first portion of the aperture in the first position and unblocks the first portion of the aperture in the second position.

摘要： An optical shutter apparatus has a shutter blade pivotable between first and second positions. The shutter blade in the first position blocks at least a portion of a light path. A stepper motor pivots the shutter blade to first or second positions. A magnetic shutter blade retention apparatus has a first movable member with a first surface, coupled to the shutter blade. A first stationary member is spaced apart from the shutter blade and is magnetically attracted to the first stationary member when the stepper motor is de-energized. When the shutter blade is pivoted to the first position, a point on the first surface is spaced apart from the first stationary member by a first distance; when the shutter blade is pivoted to the second position, the point on the first surface is spaced apart from the first stationary member by a second distance that is less than the first.

摘要： An optical shutter apparatus has a shutter blade that is movable between a first position, blocking at least a portion of an aperture and a second position spaced apart from the first position. A rotary actuator has a stator and a magnetic rotor element that is coupled to the shutter blade. The rotary actuator is energizable for moving the shutter blade between the first and second positions, wherein the rotor element rotates about an axis that lies within the stator. At least one permanent magnet is coupled to the stator and provides a magnetic field that biases the stator to provide a continuous urging force on the magnetic rotor element.

摘要： An optical shutter apparatus has at least one shutter blade that is movable between a first position blocking at least a portion of an aperture and a second position spaced apart from the first position. A linkage member is coupled to the at least one shutter blade and has a magnetic material. An actuator is coupled to the linkage member and is energizable to translate the at least one shutter blade between the first and second positions. An intermediate plate has a friction surface of a non-magnetic material. A magnet positioned away from the friction surface of the intermediate plate is disposed to urge the linkage member against the friction surface of the intermediate plate.
