    Abstract: A lens driving apparatus includes: a fixed assembly, the fixed assembly including a base frame; a movable assembly, the movable assembly including a lens holder; a set of magnets surrounding the movable assembly; three sets of coils; and a spring system attached between the movable assembly and the fixed assembly and configured to support the movable assembly and form a suspension system to allow the movable assembly to move along a first, a second, and a third orthogonal axes. The lens holder is configured to hold a lens unit, the third axis is parallel to an optical axis of the lens unit, while the first and second axes are respectively perpendicular to the third axis.

    Abstract: A lens driving apparatus includes: a fixed assembly including a base frame; a movable assembly including a lens holder configured to hold a lens unit; at least one set of magnets surrounding the movable assembly; three sets of coils configured to interact with the magnets and drive the movable assembly to move along a first, a second, and a third orthogonal axes; and a spring system attached between the movable assembly and the fixed assembly. The third axis is parallel to an optical axis of the lens unit. The first and second axes are respectively perpendicular to the third axis. The three sets of coils include a set of focusing coils and two sets of side coils. The at least one set of magnets include four magnetic members attached to inside walls of the outer casing, among which each two magnetic members are placed opposing to each other.

    Abstract: An optical arrangement includes a position sensitive optical detector, a collimated optical source, and a processor configured to monitor the inclination of an object. The collimated optical source is configured to transmit a collimated beam towards the object. The position sensitive optical detector is configured to detect the specific location of incidence of an optical signal received from the object, and the processor is configured to generate information relating to the inclination of the object from processing optical signals received at the position sensitive optical detector.
