  • Patent number: 8786864
    Abstract: A circular common-path point diffraction interference wavefront sensor includes an optical matching system, a beam-splitter, a first reflection mirror, a second reflection mirror, a first Fourier lens, a second Fourier lens, a charge-coupled device (CCD) detector, a computer system, and a two-pinhole mask having a reference pinhole and a testing window and placed at a confocal plane of the first Fourier lens and the second Fourier lens. A testing beam is divided into two beams through the beam-splitter. One beam makes the pinhole diffraction by the reference pinhole, thereby producing the approximately ideal plane wave as the reference wave. Another beam passes through the testing window almost without any attenuation as the signal wave. The spatially linear carrier frequency is introduced by adjusting the tilt angle of the beam-splitter. The present invention is adapted for all kinds of dynamic and static detection field of wavefront phase.

  • Patent number: 8631381
    Abstract: The subject application relates to a method and system for power delivery network analysis. The present disclosure is directed towards a computer-implemented method for analyzing a power delivery network (PDN) associated with an electronic circuit design. Embodiments may include extracting, using at least one processor, an electromagnetic (EM) model for each of one or more discontinuity structures associated with the circuit design and generating a three dimensional adaptive mesh model that is based upon, at least in part, the extracted EM model. Numerous other features are also within the scope of the present disclosure.
