Abstract: A wafer level camera module can be easily connected to a host device via mounting surface contacts. The module includes an electrically controllable active optical element and a flexible printed circuit that provides electrical connection between the optical element and surface conductors on a mounting surface of the module. The surface conductors can be a group of solder balls, and the module can have another group of solder balls that make connection to another electrical component of the module, such as an image sensor. All of the solder balls can be coplanar in a predetermined grid pattern, and all of the components of the device can be surrounded by a housing such that the camera module is an easily mounted ball grid array type package.

Abstract: A liquid crystal optical device has a layered structure with split liquid crystal layers having alignment surfaces that define in a liquid crystal material pre-tilt angles of opposite signs. 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: A tunable-focusing liquid crystal lens (TLCL) cell has a liquid crystal layer arranged within a cell gap defined between substrates, a layer of optically transparent material arranged between the first substrate and the LC layer, and a liquid crystal alignment layer arranged between the optically transparent layer and the LC layer. The alignment layer is provided on a third optically transparent substrate having a non-planar shape for giving a non-planar profile to the LC layer, which substrate is obtained from a flexible sheet initially provided with the alignment layer and then formed into the non-planar shape. The lens further has a first optically transparent electrode provided on the second substrate, a second optically transparent electrode provided on either or both of first and third substrates. The electrodes are arranged to generate an electric field acting on the LC layer to change the focal distance of the LC cell. Methods for fabricating such TLCL cell are also provided

Abstract: A variable angle beam control device is capable of maintaining the same color temperature of the light source regardless of the changes in the angle of the beam. The controllable light beam device has a light source with primary optics producing a low divergence light beam having an inverted angular distribution of the correlated color temperature (CCT), and a liquid crystal device with an electrically variable refractive index distribution arranged to receive said light beam and to provide a variable angle beam.

Abstract: An architectural lighting device for wall washing providing suitable beam modulation is described herein. The device combines a variable divergence beam source (a light source along with a beam stretching element) in combination with a specially designed side reflector that redirects a portion of a broadened beam back onto the wall so as to have wall illumination increase with beam divergence.

Abstract: A method of wafer level manufacturing, separating and electrical connection of liquid crystal optical devices is disclosed. An electro-optic device having at least one liquid crystal cell for providing spatially variable control of light is also described. The electro-optic device includes: a pair of opposed substrates, each substrate having a lateral extent; a pair of electrodes for applying an electric field therebetween, each electrode having a pattern and being deposited on a corresponding substrate, each electrode having an electrical contact area extending to at least one side of the corresponding substrate; a pair of alignment layers sandwiching a liquid crystal layer therebetween, the alignment layers defining a predominant orientation direction for liquid crystal molecules of the liquid crystal layer; and a liquid crystal reservoir wall defining a lateral extent of the liquid crystal layer, the liquid crystal reservoir wall being spaced from at least one side of each substrate such that each electrode electrical contact area is exposed to air in an air gap between the substrates.

Abstract: An auto-focus system employing a tunable liquid crystal lens is provided that collects images at different optical power values as the liquid crystal molecules are excited between a ground state and a maximum optical power state tracking image focus scores. An image is acquired at a desired optical power value less than maximum optical power established with the liquid crystal molecules closer a fully excited state than the maximum optical power state having the same image focus score. This drive signal employed during image acquisition uses more power than was used to achieve the same optical power value during the auto-focus scan, while actively driving the liquid crystal molecules is fast. A pause due to image transfer/processing delays after acquisition is employed to allow slow relaxation of the liquid crystal molecules back to the ground state in preparation for a subsequent focus search.

Abstract: Methods and apparatus for testing operation of a single or multiple tunable active optical device(s) operated by one or more driving electrodes are described. Test methods and apparatus are provided for device testing without necessarily requiring direct physical contact with the driving electrodes. Testing subjects devices to incident light along an optical path and to an external electric field applied to the device producing a dipolar charge distribution within the electrodes, causing the device to operate. The effect of device operation on incident light is optically sensed. The sensed effect is analyzed to identify device defects. Test methods and apparatus are provided for testing multiple unsingulated devices during fabrication employing a strip contact structure having contact strips connected to multiple devices and extending to wafer edges, such that singulating devices leaves portions of the strip contact structure exposed on device dice edges providing electrical contacts in use.
