Quantitative Optical Diffraction Tomography Imaging of Mouse Platelets

Experimental demonstration of quantitative imaging beyond Abbe's limit with optical diffraction tomography.

Optical diffraction tomography (ODT) is a recent imaging technique that combines the experimental methods of phase microscopy and synthetic aperture with the mathematical tools of inverse scattering theory. We show experimentally that this approach permits us to obtain the map of permittivity of highly scattering samples with axial and transverse resolutions that are much better than that of a ...

Optical diffraction tomography for high resolution live cell imaging.

We report the experimental implementation of optical diffraction tomography for quantitative 3D mapping of refractive index in live biological cells. Using a heterodyne Mach-Zehnder interferometer, we record complex field images of light transmitted through a sample with varying directions of illumination. To quantitatively reconstruct the 3D map of complex refractive index in live cells, we ap...

Low sidelobe limited diffraction optical coherence tomography

Optical Coherence Tomography (OCT) is a relatively new type of imaging system for medical diagnosis. Because most current OCT systems use a sharply focused beam in tissues, they have a short depth of field (high image resolution is near the focus only). In this paper, limited diffraction beams of different orders are used to increase depth of field and to reduce sidelobes in OCT. Results show t...
