  • Patent number: 10139295
    Abstract: Methods for measuring and/or mapping in-plane strain of a surface of a substrate. A grating is formed on at least a portion of the surface of the substrate. A laser is then used focused onto the grating to determine the strain on the surface by determining the variation of the grating wavelength due to the strain on the surface. The strain information is essentially carried by the grating, in terms of grating wavelength, because it varies according to the volume change of the underlying substrates. By scanning the surface grating with the small laser size, a high resolution strain map of the surface can be produced. The induced strain is related to the grating wavelength variation, which leads to the diffraction angle variation that is captured by the strain sensing measurements.

  • Patent number: 10082652
    Abstract: The present application provides a micromechanical (MEMS) based zoom lens system, for use in miniature device applications, such as miniature electronic imaging devices. The MEMS-based zoom lens system comprises at least four optical elements, or two Alvarez or Lohmann lenses, that are configured for passage of optical signals therethrough along an optical signal path. Each optical element is MEMS-driven and displaceable in a direction substantially transverse to the optical signal path. In use, the transverse displacement of the optical elements vary an overall focal length of the MEMS zoom lens system such as to provide an optical zoom function. A method of manufacturing a MEMS zoom lens system is also provided in a further aspect.
