Aspects of the present disclosure are directed to a mirror bearing for an interferometer. An example mirror bearing includes a stationary mounting member and a mobile mirror assembly configured for slidable movement relative to the mounting member along its longitudinal axis. The mounting member is configured for rigid attachment to an interferometer body. A bore extends through the mounting member along its longitudinal axis. A drive coil receiving area of the mounting member is configured to hold a drive coil coupled thereto. The mobile mirror assembly includes a tube configured to receive, at one end of the tube, an end of the mounting member. The mobile mirror assembly also includes a mirror coupled to the opposite end of the tube. A drive magnet is disposed within the tube and is configured to be received within the bore of the mounting member when the mirror bearing is in an assembled configuration.

A liquid optical module is provided, including a liquid lens driving mechanism and a liquid lens assembly. The liquid lens driving mechanism includes a fixed portion, a movable portion and a driving assembly. The movable portion is movably connected to the fixed portion. The liquid lens assembly includes a liquid lens element, a fixing member and a deforming member. The fixing member is disposed on a first fixed portion surface of the fixed portion, and the deforming member is disposed on a movable portion surface of the movable portion. The movable portion surface and the first fixed portion surface face the same direction, and when the movable portion is driven by the driving assembly to move relative to the fixed portion, the liquid lens element is deformed by the deforming member, causing the optical properties of the liquid lens element to change.

An optical system is provided, including a liquid optical module and a first optical module. The liquid optical module includes a liquid lens driving mechanism and a liquid lens assembly. The liquid lens driving mechanism includes a fixed portion, a movable portion and a first driving assembly configured to drive the movable portion to move relative to the fixed portion. The liquid lens assembly includes a liquid lens element, a fixing member and a deforming member. The first optical module is disposed in a receiving space of the fixed portion and includes: a first optical element and a first optical driving mechanism. When the movable portion is driven by the driving assembly to move relative to the fixed portion, the liquid lens element is deformed via the deforming member, causing the optical properties of the liquid lens element to change.

The present invention relates to an aperture unit having an optical axis. The aperture unit includes a fixed portion, a guiding element, a first blade and a driving assembly. The guiding element is movably connected to the fixed portion, and the first blade is movably connected to the guiding element and the fixed portion. The driving assembly is disposed on the guiding element for driving the guiding element to move relative to the fixed portion in a first moving dimension. When the guiding element moves relative to the fixed portion in the first moving dimension, the first blade is driven by the guiding element to move relative to the fixed portion in a second moving dimension, and the first moving dimension and the second moving dimension are different.

A movable unit of an optical module having an image shake correction function is supported by a gimbal mechanism so as to be rotatable around a first axis R1 and a second axis R2. The movable body is driven by a shake-correction magnetic drive mechanism including magnets and fixed to the movable body. The movable body further includes a lens-moving magnetic drive mechanism to move a lens module in an optical axis direction. The lens-moving magnetic drive mechanism includes a lens-moving coil fixed to the lens module 7 and a lens-moving magnet disposed radially outward of the lens-moving coil. The magnets and also serve as the lens-moving magnet and are disposed radially outward of a triaxial intersection.

A camera and a terminal including the same are disclosed. The camera according to an embodiment of the present invention includes: a first prism apparatus to reflect a first input light input in a first direction to a second direction; a second prism apparatus to reflect a second input light input in the first direction to the second direction, and output the reflected second input light to the first prism apparatus; a lens apparatus to receive the first input light from the first prism apparatus or the second input light from the second prism apparatus; and an image sensor to generate an image signal based on the first input light or the second input. Accordingly, it is possible to implement a slim camera that can use a single image sensor with respect to a plurality of cameras at the time of front photographing or rear photographing.

An optical element includes a plate portion including a reflecting surface on an upper surface in a direction of a vertically extending central axis, a shaft that extends in a direction of a first axis intersecting with the central axis and is fixed to a lower surface of the plate portion, a magnet below the shaft in the direction of the central axis, and plates that fix the plate portion and the shaft, the plate portion including a protruding portion that extends downward in the direction of central axis from a lower surface, the plate including a shaft fixing portion to which the shaft is fixed and a plate portion fixing portion to which the plate portion is fixed, the plate portion fixing portion being fixed to the protruding portion.

An optical member driving mechanism is provided, including a movable portion, a fixed portion, and a driving assembly. The movable portion is connected to an optical member. The fixed portion has an accommodating space, and the optical member is received in the accommodating space. The movable portion is movable relative to the fixed portion. The driving assembly is configured to drive the movable portion to move relative to the fixed portion.

The disclosure relates to an optical module with first and second components, a supporting structure and an anticollision device. The first component is supported by the supporting structure and is arranged adjacent to and at a distance from the second component to form a gap. The supporting structure defines a path of relative movement, on which the first and second components move in relation to one another under the influence of a disturbance, a collision between collision regions of the first and second components occurring if the anticollision device is inactive. The anticollision device includes a first anticollision unit on the first component, which produces a first field, and a second anticollision unit on the second component, which is assigned to the first anticollision unit and produces a second field.

Data sets DS4 to DS6 each consisting of plural linear functions obtained by approximating an output characteristic of a Y-axis rotation position detection Hall element H2 and a data set DS2 consisting of plural linear functions obtained by approximating an output characteristic of an and the X-axis position detection Hall element H1 are stored for each of plural positions in a direction X in a ROM of a memory. A system controller detects a position of a movable member in the direction X based on the data set DS2 and an output signal of the X-axis position detection Hall element H1, then selects the data set corresponding to the position among the data sets DS4 to DS6, and detects a position of the movable member in a direction Y based on the selected data set and an output signal of the Y-axis rotation position detection Hall element H2.
