Four liquid crystal layers can provide two directions of linear polarization. In the case of a lens, the device can be a gradient index lens, and the alignment surfaces can have a spatially uniform pre-tilt.

Abstract: The present invention is a compact lens system for use as a wide-field photographic objective with small format digital image sensors having a pixel dimension less than 0.010 mm. The f-number of the lens system is 2.9740, and the effective focal length of the system is 3.85 mm. The full angular field of view of the lens system is 61 degrees, and the chief ray incidence angles on the image plane are less than 18 degrees. The system comprises three plastic lenses, each having two aspheric surfaces. At least one of the aspheric surfaces in the system is coated with a multilayer infrared cut-off filter for blocking infrared wavelengths from the image sensors. The lens system has a reduced sensitivity to manufacturing tolerances, particularly lateral misalignment of optical elements and surfaces.

Abstract: A camera module and method for focusing a tunable lens configured to continuously vary its optical power in response to a drive signal. A drive circuit generates the drive signal so that the tunable lens performs a continuous scan of its optical power. An image sensor is configured to acquire light images passing through the tunable lens, and to convert the light images to image signals during the continuous scan. A processor is configured to generate focus scores of the acquired light images using the image signals during the continuous scan. The processor is configured to determine from the focus scores a peak focus score achieved or achievable, and to instruct the drive circuit to adjust the drive signal so that the tunable lens settles at a value of the optical power that corresponds to the peak focus score.

Abstract: A focus free camera module uses fixed lenses within a housing that are combined with an electrically controllable active optical element, such as a tunable liquid crystal lens. The fixed lenses provide a desired amount of optical power, but the manufacturing tolerances of the module are insufficient to ensure a proper focus of an image on an image sensor. The active optical element is therefore used to compensate for any variations in the optical power to achieve the desired focus. To ensure an effective compensation, the module may be constructed so that, when the variation in optical power due to manufacturing tolerances is at a maximum, the desired focus is achieved when the active optical element is at zero optical power. All other variations may then be compensated by adjusting the active optical element to increase its optical power.
Abstract translation: 无焦距相机模块在外壳内使用固定透镜，其与诸如可调谐液晶透镜的电可控有源光学元件组合。 固定透镜提供所需量的光功率，但是模块的制造公差不足以确保图像在图像传感器上的适当聚焦。 因此，有源光学元件用于补偿光功率中的任何变化以实现期望的焦点。 为了确保有效的补偿，模块可以被构造成使得当由于制造公差而导致的光功率变化最大时，当有源光学元件处于零光功率时，实现期望的聚焦。 然后可以通过调节有源光学元件来增加其光功率来补偿所有其它变化。
