  • Patent number: 10718607
    Abstract: Illustrative embodiments of determining geometric characteristics of reflective surfaces are disclosed. In at least one illustrative embodiment, a method of determining geometric characteristics of reflective surfaces includes sensing electromagnetic waves with a sensor, where the electromagnetic waves have been reflected off a reflective surface of a specimen from a target structure including a feature point. The method further includes determining a displacement of the feature point of the target structure indicated by the sensed electromagnetic waves relative to reference data indicating a reference location for the feature point and determining a surface slope of a point of the reflective surface based on the determined displacement of the feature point of the target structure.

  • Patent number: 10080011
    Abstract: Embodiments of the present disclosure provide for a light field imaging apparatus and method. In one embodiment, an apparatus may comprise one or more imaging modules that may include a lens array, to receive a light field of a surface of an object or scene, and a fiber optic image transferring device having a first end and a second end. The fiber optic image transferring device may be coupled with the lens array at the first end, to transfer the light field to the second end. The apparatus may further include an image sensor coupled with the second end of the fiber optic image transferring device, to register the transferred light field and provide the registered light field for processing. Other embodiments may be described and/or claimed.
