  • METHOD FOR MEASURING SURFACE CHARACTERISTICS IN OPTICALLY DISTORTING MEDIA
    Publication number: 20240044641
    Abstract: Provided is a method for measuring surface characteristics of at least a portion of an object, including providing a light source; generating a first interference pattern on the at least a portion of the object; capturing an image of the first interference pattern; shifting the phase of the light source to generate a second interference pattern; capturing an image of the second interference pattern; filtering distortion from the interference patterns; extracting a wrapped phase of the at least a portion of the object based on the images; unwrapping the wrapped phase of the at least a portion of the object to generate an unwrapped phase; identifying a computed depth map distance to the at least a portion of the object; and fitting an ideal part to the computed depth map of the at least a portion of the object to measure the surface characteristics.

  • Optical devices and methods of manufacture of optical devices
    Patent number: 8934744
    Abstract: A method for performing a multi-stage dilation of optical fibers is described, the method comprising performing successive dilation steps such that the adiabatic condition is maintained throughout the fiber. There is also described various optical devices employing such multi-stage dilated optical fibers, as well as methods of manufacture of the optical devices.
