    摘要: An interferometric tracking device (100) includes image dividers (120, 140, 160) arranged to form an optical cascade, with one of the image dividers being an incident image divider (120) for the optical cascade and one or more of the image dividers being one or more exit image dividers (160) for the optical cascade. Each of the image dividers (120, 140, 160) splits incident light into a plurality of non-parallel orthogonally polarized beams, the beams from the incident image divider (120) cascading through the other image dividers (140, 160) in the cascade. Each of a plurality of shearing interferometers (130, 150) is optically coupled between optically adjacent image dividers (120, 140, 160) in the cascade. The orthogonally polarized beams from the one or more exit image dividers (160) are imaged onto one or more focal plane arrays (190).

    摘要: An integrated circuit and a method of making the same. The integrated circuit includes a semiconductor substrate having a major surface. The integrated circuit also includes a directional light sensor. The directional light sensor includes a plurality of photodetectors located on the major surface. The directional light sensor also includes one or more barriers, wherein each barrier is positioned to shade one or more of the photodetectors from light incident upon the integrated circuit from a respective direction. The directional light sensor is operable to determine a direction of light incident upon the integrated circuit by comparing an output signal of at least two of the photodetectors.
