Embodiment Construction

[0020] Description will be made below with reference to the accompanying drawings. It is understood that other structures and / or embodiments may be used without departing from the scope of the present invention.

[0021] The liquid lens unit is able to change the optical path without relying on the mechanical movement of the liquid unit. A liquid lens unit comprising first and second contacting liquids may be configured such that a contacting optical surface between the contacting liquids has a variable shape, which may be substantially symmetrical with respect to an optical axis of the liquid lens unit. A plurality of lens elements may be aligned along a common optical axis and configured to collect radiation emanating from the object-side volume and transmitted to the image-side volume. A liquid lens cell may be inserted into an optical path formed by a plurality of lens elements aligned along a common optical axis. The optical axis of the liquid lens unit may be parallel ...

Abstract

Liquid lens cells are used in a variable power optical system. In one embodiment, a stop is located between a first lens group comprising at least a first liquid lens cell and a second lens group comprising at least a second liquid lens cell. In one embodiment, a liquid lens cell controls an incident angle of light rays on an image surface.

Description

[0001] related application [0002] This application claims priority to US Provisional Application No. 61 / 168,524, filed April 10, 2009, which is incorporated herein by reference in its entirety and made a part of this specification. Background technique [0003] The present invention relates to variable power optical systems employing liquid optics. [0004] Zoom lenses usually have three or more moving lens groups to achieve zoom and focus functions. A mechanical cam connects two movable lens groups for zooming, and a third movable lens group can be used for focusing. [0005] The zoom range is determined in part by the range of movement of the movable lens element. Larger zoom ranges may require additional space for lens element movement. [0006] Image sensors such as Charge Coupled Device (CCD) sensors and CMOS Image Sensors (CIS) collect light through small photosensitive areas such as photodiodes. Image sensors can use microlenses to improve photosensitivity by coll...
