Abstract:
1. An apparatus for determining surface topology of at least a portion of a three-dimensional structure, the apparatus comprising: a probing member having an end face; an illumination unit configured to transmit a parent light beam along an optical path in the probing member; a module positioned in the optical path and configured to generate a plurality of incident light beams; an optical system configured to focus the plurality of incident light beams at a focal plane forward of the end face; a detector unit configured to measure a characteristic of a plurality of returned light beams that are generated from illuminating the portion of the three-dimensional structure with the plurality of incident light beams; and a processor coupled to the detector unit and configured to determine a surface topology of the three-dimensional structure based at least in part on the measured characteristic of the plurality of returned light beams.
