摘要:
Varifocal lens for camera module incorporated in wireless mobile communication device is provided. The varifocal lens includes: a membrane; a frame which is fixed to the membrane and has a receiving hole formed in the middle; a transparent substrate which is fixed to the frame to seal optical fluid received in the receiving hole; one or more actuators to change a curvature of a fluid lens part by bending the circumference of the fluid lens part formed around a central portion of the receiving hole; and a restriction lessening member which is adapted to lessen a restrictive force of an edge of the fluid lens part, is made of a transparent material, has with an area smaller than the fluid lens part to correspond to an inner side of the fluid lens part except the edge of the fluid lens part, and has a larger Young's modulus than the membrane.

A pattern projecting apparatus usable with a three-dimensional imaging apparatus includes a light generator which emits a light beam, and a pattern adjusting unit disposed in front of the light generator. The pattern adjusting unit forms a projection pattern on an object, and adjusts a focus of the light beam emitted from the light generator.

A varifocal optical device is provided. The varifocal optical device includes an optical lens, an actuator unit connected with the optical lens and having two areas that are bending-deformed in opposite directions to each other when a voltage is applied thereto, and a supporting unit to support the actuator unit, so that a focus of the optical lens is varied by the bending deformation when the voltage is applied to the actuator unit. Thereby, a driving displacement of the varifocal optical lens can be maximized.

A liquid optical lens which changes a focus due to a change in a shape of a translucent elastic membrane according to a change in a fluid pressure of a lens chamber and a manufacturing method thereof are provided. The liquid optical lens forms a dampproof coating membrane on the translucent elastic membrane to prevent a fluid from permeating through the translucent elastic membrane and a swelling phenomenon of the translucent elastic membrane.
