  • Publication number: 20190064415
    Abstract: A cube wire grid polarizer or an embedded wire grid polarizer can include an adhesive-free, direct bond between the wire grid polarizer and piece(s) of glass. Consequently, index of refraction mismatch can be avoided and the polarizer can have improved high temperature tolerance. The polarizer can include multiple layers over the wire grid polarizer, with the top of these layers polished, then directly bonded to the piece of glass. Material of the top layer can be selected such that thickness of this layer is not critical, thus allowing polishing.

  • Patent number: 10189426
    Abstract: The present application discloses a method and apparatus for operating a field-programmable gate array (FPGA) board in a driverless vehicle. The method according to a specific embodiment includes: collecting driving scenario information on a driving scenario of the driverless vehicle; determining, based on the driving scenario information, a speed at which the driverless vehicle executes a computing operation in the driving scenario; comparing the speed with a speed threshold; switching a working mode of the FPGA board in the driverless vehicle executing the computing operation to reduce power consumption of the FPGA board, in response to the speed being lower than the speed threshold. This embodiment implements the adaptive adjustment of the working mode of the FPGA board, thereby reducing the overall power consumption.

  • Patent number: 10194139
    Abstract: A procedure to calibrate a depth-disparity mapping for a plenoptic imaging system. In one aspect, one or more test objects located at known field positions and known depths are presented to the plenoptic imaging system. The plenoptic imaging system captures plenoptic images of the test objects. The plenoptic images include multiple images of the test objects captured from different viewpoints. Disparities for the test objects are calculated based on the multiple images taken from the different viewpoints. Since the field positions and depths of the test objects are known, a mapping between depth and disparity as a function of field position can be determined.

  • Publication number: 20180224552
    Abstract: A system and method for compressed-sensing ultrafast photography for two-dimensional dynamic imaging is disclosed. The system and method may capture non-repetitive time-evolving events at up to about 100 billion frames per second. In an aspect, a digital micromirror device (DMD) may be added as the spatial encoding module. By using the DMD and applying the CUP reconstruction algorithm, a conventional 1D streak camera may be transformed to a 2D ultrafast imaging device. The resultant system may capture a single, non-repetitive event at up to 100 billion frames per second with appreciable sequence depths (up to about 350 frames per acquisition). In another aspect, a dichroic mirror may be used to separate signals into two color channels, and may further expand CUP's functionality into the realm of four-dimensional x, y, k, t ultrafast imaging, maximizing the information content that may be simultaneously acquired from a single instrument.
