Segmenting the optical system into stationary and movable groups lowers moving mass to boost autofocus speed while correcting sagittal coma aberration.
An image sensor controls area-specific exposure times to support contrast-based focus evaluation.
Immiscible sealing liquid centers droplet on central axis, resolving manufacturing precision trade-offs in electrowetting lenses.
Lateral barrel insertion into a lens carrier eliminates sliding walls, enabling device miniaturization while maintaining structural stability.
Ridges deform with temperature changes to counteract thermally induced optical characteristic variations without active actuators.
