Angular light scattering studies using low-coherence interferometry
A modified Michelson interferometer is used to measure path-length resolved angular distributions of light backscattered by turbid media. The path length resolution is obtained by exploiting the coherence properties of a broadband source. The angular distribution is mapped out using a simple optical system to scan the angle at which the reference field intersects the detector plane. Angular sca...
متن کاملNovel Crystalline-Waveguide Broadband Light Sources for Interferometry
In recent years, broadband fiber interferometers have become very popular as basic instruments used in optical lowcoherence reflectometry for diagnostics of fiber and integrated optics devices or in optical coherence tomography (OCT) for imaging applications in the biomedical field. The longitudinal resolution of such instruments is inversely proportional to the optical bandwidth of the light s...
متن کاملFourier-domain low-coherence interferometry for light-scattering spectroscopy.
We present a novel method for obtaining depth-resolved spectra for determining scatterer size through elastic-scattering properties. Depth resolution is achieved with a white-light source in a Michelson interferometer with the mixed signal and reference fields dispersed by a spectrograph. The spectrum is Fourier transformed to yield the axial spatial cross correlation between the signal and ref...

متن کاملDispersion cancelled low coherence interferometry
Even-order dispersion cancellation, an effect previously identified with frequencyentangled photons, is demonstrated experimentally for the first time with a linear, classical interferometer. A combination of a broad bandwidth laser and a high resolution spectrometer was used to measure the intensity correlations between anti-correlated optical frequencies. Only 14% broadening of the correlatio...
