Optical system with shutter assembly having an integral shutter-mounted actuator

An optical system comprising a shutter assembly including

• a support;
• a shutter movable with respect to the support;
• and
• a shutter drive mechanism including
• a first magnet affixed to a first one of the support and the shutter, and
• a first electromagnet structure affixed to a second one of the support and the shutter and comprising a first-structure first electromagnet wherein the first magnet and the first-structure first electromagnet are positioned such that activation of the first-structure first electromagnet causes the first magnet to move relative to the first-structure first electromagnet, wherein the first electromagnet structure further includes a first-structure second electromagnet, wherein the first magnet and the first-structure second electromagnet are positioned such that activation of the first-structure first electromagnet and the first-structure second electromagnet both cause the first magnet to move in the same direction relative to the first-structure first electromagnet.

An optical system comprising a shutter assembly including

• a stationary support;
• a shutter pivotably mounted upon and movable with respect to the support;
• and
• a shutter drive mechanism including
• a permanent first magnet affixed to the shutter,
• a first electromagnet structure affixed to the support facing a first side of the shutter and comprising a first-structure first electromagnet, wherein the permanent first magnet and the first-structure first electromagnet are positioned such that activation of the first-structure first electromagnet causes the permanent first magnet to move relative to the first-structure first electromagnet, and
• a second electromagnet structure affixed to the support facing a second side of the shutter and comprising a second-structure first electromagnet, wherein the permanent first magnet and the second-structure first electromagnet are positioned such that activation of the second-structure first electromagnet causes the permanent first magnet to move relative to the second-structure first electromagnet in a same direction as the activation of the first-structure first electromagnet.
