Analysis of artificial opals by scanning near field optical microscopy
(American Institute of Physics, 2011-04)
Herein we present a detailed analysis of the optical response of artificial opal films realized employing a near-field scanning optical microscope in collection and transmission modes. Near-field patterns measured at the ...
Harmonic demodulation and minimum enhancement factors in field-enhanced near-field optical microscopy
(Wiley Blackwell Publishing, Inc, 2015-01)
Field enhanced scanning optical microscopy (FESOM) relies on the design and fabrication of plasmonic probes which had to provide optical and chemical contrast at the nanoscale. In order to do so, the scattering containing ...
Experimental verification of the spectral shift between near- and far-field peak intensities of plasmonic infrared nanoantennas
(American Physical Society, 2013-03)
Theory predicts a distinct spectral shift between the near- and far-field optical response of plasmonic antennas. Here we combine near-field optical microscopy and far-field spectroscopy of individual infrared-resonant ...

3-D reconstruction by extended depth-of-field in failure analysis - Case study I: Qualitative fractographic investigation of fractured bolts in a partial valve
(Pergamon-Elsevier B.V. Ltd, 2010-03-01)
Extended depth-of-field 3-D reconstruction is an image processing based technique associated to optical microscopy for qualitative or quantitative analysis of surfaces topographies. It is proposed here as a low-cost ...
Methods of Fourier optics in digital holographic microscopy
(ELSEVIER SCIENCE BV, 2008)
In this paper, processing methods of Fourier optics implemented in a digital holographic microscopy system are presented. The proposed methodology is based on the possibility of the digital holography in carrying out the ...
