There have been three basic approaches to optical tomography since the early 1980s: diffraction tomography, diffuse optical tomography and optical coherence tomography (OCT). Optical techniques are of particular importance in the medical field, because the ...
The infrared (IR) absorption of a biological system can potentially report on fundamentally important microchemical properties. For example, molecular IR profiles are known to change during increases in metabolic flux, protein phosphorylation, or proteolyt ...
We present a new light source for parallel Optical Coherence Tomography (OCT) based on multiple waveguides written in Ti:sapphire. Each channel can generate a spectrum of 174 nm bandwidth centered at 772 nm, with an optical power on sample of 30 mu W. A sy ...
In this thesis new imaging approaches for optical microscopy are proposed and studied. They are based on the use of dynamic structured illumination in combination with a demodulation detection concept employing CMOS image detectors. Two particular implemen ...
Micro-optical electro-mechanical systems (MOEMS) technology, making use of existing silicon based fabrication techniques shows great potential for making complete miniaturized hybrid devices. Such technology has been used to make a Fourier transform spectr ...
A new numerical a posteriori dispersion compensation technique for partial coherence interferometry and optical coherence tomography depth-scan signals is presented. This technique is based on numerical correlation of the depth-scan interferometer signal w ...
The main purpose of this thesis is to explore a new concept of SNOM probes. In order to produce more reliable and reproducible tips, we propose to graft a single gold particle of 60 nm diameter onto the aperture of a SNOM probe. The expected advantage of s ...
LP01-LP02 mode converters based on UV-written intracore gratings have been fabricated for chromatic-dispersion compensation. The mode converters operate in transmission at wavelengths near 1550 nm with spectral bandwidths of 14-25 nm and coupling efficienc ...
Polarization dispersion is one of the effect which can give rise to data rate limitation. An actual optical link can be installed using different appended fibres, manufactured by different producers, processing techniques or batches. Knowing the polarizati ...
LiF films have been grown on silicon substrate, irradiated with soft x-rays to create fluorescent regular micrometric-spaced arrays based on colour centres, and studied by Scanning Near-field Optical Microscope (SNOM). Strong variations in the local reflec ...
