History

Work topics

• Propagation and image formation through media with structured indexes of refraction, such as anisotropic media, GRIN media (Graded Index of refraction), optical fibers, etc.
• Perturbations on the modal structure of a laser beam due to the propagation in a turbulent atmosphere at laboratory level.
• Statistical deviations of the laser beam propagation produced by atmospheric perturbations in experiments at laboratory and fields levels.
• Statistical deviations of the auto-image formation of a grade produced by the atmospheric
• Transmission of a laser beam by turbid media.
• Image formation by turbid and turbulent media using confocal scanning laser microscopy.

The most relevan works

• It was found that the index of refraction of  air has a fractional Brownian behaviour.
• The auto-images formation was explained by using the Feynman formalism.
• A method for measuring the lacunarity of a fractal structure by using difraction was found.
• Morphological variations of alive cells were determined by the introduction of a microscopical interferential technique.
• Topographic variations of human foot were achieved in footstep by means of structured illumination.
• A The basis for the formation of moiré by using hidden or implicit gradeswas established and an enlargement of the distance measurement was conducted.

Available equipment

• Visible and infrared lasers.
• A complete Optical bench and a complete optical table.
• Detectors, photographic cameras, videocameras, CCD cameras.
• Computers for calculation and simulation.
