Dynamic full-field optical coherence tomography: 3D live-imaging of retinal organoids [PDF]
, 2019 Optical coherence tomography offers astounding opportunities to image the complex structure of living tissue, but lacks functional information. We present dynamic full-field optical coherence tomography to image living human induced pluripotent stem cell-derived retinal organoids non-invasively.

Role of spatial coherence in polarization tomography [PDF]
, 2005 We analyze an experimental setup in which a quasi-monochromatic spatially coherent beam of light is used to probe a paraxial optical scatterer. We discuss the effect of the spatial coherence of the probe beam on the Mueller matrix representing the scatterer.

Acousto-optical coherence tomography with a digital holographic detection scheme [PDF]
Optics Letters 37, 15 (2012) 3216-3218, 2012 Acousto-optical coherence tomography (AOCT) consists in using random phase jumps on ultrasound and light to achieve a millimeter resolution when imaging thick scattering media. We combined this technique with heterodyne off-axis digital holography. Two-dimensional images of absorbing objects embedded in scattering phantoms are obtained with a good ...

Optical Tomography of Photon-Added Coherent States, Even/Odd Coherent States and Thermal States [PDF]
, 2011 Explicit expressions for optical tomograms of the photon-added coherent states, even/odd photon-added coherent states and photon-added thermal states are given in terms of Hermite polynomials. Suggestions for experimental homodyne detection of the considered photon states are presented.

Extraction of depth moments by exploiting the partial coherence of radiation [PDF]
, 2015 We retrieve depth information (moments) of an object using partially coherent fields and defocus induced holographic contrast. Our analysis leads to a form of tomography that does not require sample or source rotation. The tomography method presented here is performed with only two in-line images.

Experimental Demonstration of Spectral Intensity Optical Coherence Tomography [PDF]
arXiv, 2015 We demonstrate experimentally quantum-inspired, spectral-domain intensity optical coherence tomography. We show that the technique allows for both axial resolution improvement and dispersion cancellation compared to conventional optical coherence tomography.

Systems and Methods for the Spectral Calibration of Swept Source Optical Coherence Tomography Systems [PDF]
arXiv, 2019 This dissertation relates to the transition of the state of the art of swept source optical coherence tomography (SS-OCT) systems to a new realm in which the image acquisition speed is improved by an order of magnitude. With the aid of a better quality imaging technology, the speed-up factor will considerably shorten the eye-exam clinical visits which ...

Blind dispersion compensation for optical coherence tomography [PDF]
arXiv, 2004 We propose a numerical method for compensating dispersion effects in optical coherence tomography that does not require a priori knowledge of dispersive properties of the sample. The method is based on the generalized autoconvolution function, and its principle of operation can be intuitively visualized using the Wigner distribution function formalism.

Complete Two-dimensional Muellermetric Imaging of Biological Tissue Using Heterodyned Optical Coherence Tomography [PDF]
arXiv, 2010 A polarization-sensitive optical coherence tomography system based on heterodyning and filtering techniques is built to perform Stokesmetric imaging of different layers of depths in a porcine tendon sample. The complete 4\times4 backscattering Muellermetric images of one layer are acquired using such a system.

Real-time High-Resolution Mid-infrared Optical Coherence Tomography [PDF]
Light: Science & Applications volume 8, Article number: 11 (2019), 2018 The potential for improving the penetration depth of optical coherence tomography systems by using increasingly longer wavelength light sources has been known since the inception of the technique in the early 1990s. Nevertheless, the development of mid-infrared optical coherence tomography has long been challenged by the maturity and fidelity of ...
