The disclosure provides a method and a system for multi-lens module alignment, adapted to perform alignment on a multi-lens module having at least a first lens and a second lens during its manufacturing stage, where the method includes the following steps. A calibration object is first captured by using the first lens and the second lens to accordingly generate intrinsic parameters and external parameters of the first lens and the second lens, where the external parameters of the first lens and the second lens are associated with a common reference coordinate system. A target object is next captured by using the first lens and the second lens, and captured images of the target object are processed by using the intrinsic parameters and the external parameters to generate rectified images. The first lens and the second lens are adjusted and aligned according to the rectified images.

An image capture device including a bayonet, an integrated sensor and lens assembly (ISLA), and fasteners. The bayonet includes a mounting flange that connects the bayonet to a first surface the image capture device, a central portion, and connection recesses located within the central portion. The ISLA includes: a forward end that aligns with the connection recesses; a rearward end; internal lenses located within the ISLA and being aligned along an optical axis; and an integrated sensor connected to the rearward end and located along the optical axis. The fasteners extending through the central portion into the forward end of the lens assembly to connect the ISLA to the bayonet.

An optical device includes: an optical element; a housing unit configured to accommodate the optical element; a support part configured to pivotally support the optical element to be tiltable with respect to the housing unit; a piezoelectric element configured to connect the optical element and the housing unit to each other; and an electrode arranged at the piezoelectric element.

Examples are disclosed herein that relate to linear magnetic actuators in camera devices. One example provides a camera device comprising an optical sensor, a lens positioned a variable distance away from the optical sensor, a linear magnetic actuator having a coil and a magnet configured for linear relative movement upon driving of current, and an actuator coupling structure. The actuator coupling structure couples the linear magnetic actuator to the lens, such that the lens moves in response to the movement of the linear actuator.

A method for fabricating millimeter and sub-millimeter size lenses using a high viscosity curable liquid, such as epoxy. The method comprises dispensing a predetermined volume of the curable liquid onto a substrate. The curable liquid preferably has a viscosity higher than 100 cps. Additionally, to reduce spherical aberration, the curable liquid can be cured upside down to leverage the effects of gravity.

A device and a method for the coating of lenses. The lenses which are to be coated are arranged in pairs over parallel tubular targets such that they each overlap both a homogeneous and an inhomogeneous removal region of the target and the lenses rotated so that an especially uniform coating can be achieved.

Disclosed herein is a camera module comprising: a circuit board; a frame coupled to the circuit board; an image sensor on the circuit board; a bobbin on the frame, a plurality of lenses being inside the bobbin; a coil wound on the bobbin, the bobbin moving to two directions based on a current applied to the coil; a magnet configured to interact the coil; and a yoke on the frame, the magnet being at an inner side of the yoke, wherein the bobbin moves to a first direction when a forward current is applied to the coil and to a second direction when a reverse current is applied to the coil.

In one embodiment, a gimbal adjustment system and an associated method for adjusting the position of an object. The system comprises a base, a plate and a shaft including a pivot attached to the plate. The pivot has a point of contact with the plate in a joint about which the plate is rotatable.
