ELECTRICALLY CONTROLLABLE OPTICAL ELEMENT MADE OF AN OPTICALLY ISOTROPIC LIQUID, IN PARTICULAR LENS, AND METHOD FOR THE PRODUCTION THEREOF ON THE BASIS OF LIQUID COMPOSITES
In order to configure or produce an electrically controllable optical element on the basis of the electro-optic Kerr effect with a low threshold and operating voltage, a minimized temperature dependence of the effect and a low response time, the Kerr liquid according to the invention comprises a mixture of rod-shaped molecules and non-rod-shaped molecules as active composites, a thin layer having a pre-stamping, wide-mesh, anisotropic network between structured and/or planar conductive layer applied to a substrate thus configure a thin-film cell in such a way that without electric field the state of the active composite of the Kerr liquid in the working temperature region RT is isotropic and that by electrically continuous adjustment, of the voltage U or by a switching-on or switching-off a change the voltage U, in the optical element a voltage-induced phase shift or a refractive index deviation is generated and the light passes through an electrode gap perpendicular to the electrodes.
Directional optical receiver
An optical phased array (OPA) receiver selectively detects, measures and differentiates between the amplitudes and directions of signals received from different directions. Because the OPA changes the direction that it looks toward electronically and without the use of any mechanical movements, the OPA is fast, has an enhanced sensitivity, and can be used in a wide variety applications, such as lens-free imaging systems. The OPA is adapted to dynamically control the array of optical elements and focus on the area of interest. The OPA achieves a higher numerical aperture compared to imaging systems that use conventional lens, thereby effectively maintaining a relatively large field of view and collection area concurrently. The OPA may be readily scaled by increasing its array size. Furthermore, because the OPA is relatively flat, it is ideally suited for small form factor applications such as cell phones and tablets.

The present application discloses a 3D imaging method and apparatus, which divide a source 3D image light into two polarized light beams carrying image information through a birefringence effect, adjust optical paths of the two polarized light beams obtained through birefringence, and control the two polarized light beams to be alternately irradiated, thereby achieving 3D imaging; since the implementation of the above imaging method only requires one imaging apparatus having corresponding functions, the present application can simplify the system structure and reduce the system cost relative to a conventional 3D projection technology that requires two imaging devices; moreover, a viewer can directly see, with no need to wear corresponding 3D glasses, a 3D image due to the parallax caused by alternate irradiation of two polarized light beams carrying image information out of a projection device. As a result, the investment in configuring 3D glasses can be saved and the system cost is further reduced.
