Research summary

Conducted research in different fields, such as: optical coherence tomography (OCT), confocal microscopy, imaging the eye, supercontinuum and swept sources for OCT, combining adaptive optics with OCT, fiber optic sensing, photoelectron statistics, multichannel fibre optic digital correlator, channelled spectrum techniques for distance measurements, fibre Bragg gratings for hydrophones, optical communications, secure optical communications, Faraday sensing, ancillary measuring systems, light modulation by electrooptic crystals, nonlinear optical interactions, laser mode - locking and instabilities in lasers, optical bistability, laser applications in medicine, radioelectronics, characterization of optoelectronic devices and design of optoelectronic measuring equipment.

Innovative results in OCT research:

En-face OCT image of the retina (1997), OCT/SLO, a combined OCT/scanning laser ophthalmoscopy (SLO) instrument for the retina (1998), OCT/SLO/indocyanine green angiography imaging system for the retina (2005), OCT/SLO combined with adaptive optics for the retina (2006), En-face OCT with no external modulator, using scanner modulation (1996), Simultaneous OCT imaging from several depths (1997), Fourier domain OCT with absolute no mirror terms, using Talbot bands (2006), Method for topography of curved objects, including the cornea (2008), Scanning head for OCT despeckle (2010), Shack-Hartmann wavefront sensor with hardware coherence gating (2010), OCT for displaying underdrawings (2005) with applicability in art conservation and forensic art, Master/Slave OCT technology (spectral domain en-face OCT with higher sensitivity, better axial resolution than the conventional technology, no need for calibration of data) (2013), akinetic dual mode locked swept laser at over 1 MHz tuning rate. Other contributions to the OCT field are: the introduction of the concept of OCT with adjustable depth resolution (1999), development of a transmissive spectral delay line for OCT with only two passes on the dispersor (2005) and the analysis of signal to noise ratio with introduction of two noise bandwidth definitions for spectral splitters to handle large bandwidths, as required by ultra-high resolution OCT (2004).
