Abstract: A high performance, low-cost automotive radar is designed by mounting receivers around a 3D printed Luneburg lens. With this configuration, the antenna radiation pattern is maintained for all angles, (which means no beam deformation). Further, the present radar is capable of performing detection at all azimuth and elevation angles with high angle resolution and broadband operation. The radar adaptively adjusts its spatial sensing pattern, sweeping frequency band, pulse repetition frequency and coherent processing interval according to the environment. This is accomplished by initially performing a rough scan, which updates sensing results via a narrow bandwidth waveform and wide beam scanning. When interested objects are identified, a high-resolution detailed scan is performed in a specific region of interest. In this way, a much more effective detection can be obtained.

Abstract: A light projection system for projecting full-resolution, high quality images into different directions.

Abstract: A light-combining optical imager includes a spatially-curved waveguide-body complemented with at least two and preferably at least three holographic layers disposed on the surface(s) of the waveguide-body to couple light into the waveguide-body, optionally redirect its propagation inside the waveguide-body, and outcouple light from the waveguide body to form an optical image with reduced aberrations and—when desired—while expanding the pupil size of the imager upon propagation of light through the waveguide-body to achieve a one-to-one optical conjugation between an object and an image. At least one of the holographic layers includes potions having different diffraction efficiencies. At least one of the holographic layers is optionally configured to operate as a non-zero optical power lens element. Spatial separations between the holographic layers judiciously relate to dimensions of the portions of the holographic layers to achieve the desired result.

Abstract: A flexible polymer waveguide array structure serves as a stitch or jumper on an optical printed circuit board (OPCB). The flexible polymer waveguide array structure can be attached to the OPCB so that it can provide a chip-to-OPCB optical connection. The waveguide(s) in the flexible polymer waveguide array structure may be prefabricated before the flexible polymer waveguide array structure is attached to the OPCB. Alternatively, the waveguides may be fabricated after the flexible polymer waveguide array structure has been attached to the OPCB. The waveguide(s) may be subsequently formed using a printing process such as photolithography. As a consequence of forming the waveguide(s) after attachment of the flexible polymer waveguide array to the OPCB, the precision in the lateral alignment that is required when placing the flexible polymer waveguide array structure on the OPCB is generally significantly less than is required when the waveguide(s) are prefabricated.
