We report on the initial results of the first automated classifier to distinguish basal cell carcinomas and healthy skin using polarization sensitive optical coherence tomography (PS-OCT) with a sensitivity and specificity of 84.2% and 85.8%.
The differential Mueller matrix offers useful insight into the polarization properties of biological tissue imaged with polarization sensitive optical coherence tomography. We present the theory and experimentally demonstrate local depolarization in addition to local retardation.
A quantitative polarization sensitive optical coherence tomography (PS-OCT), so called Jones matrix (JM-) OCT is presented. This system measures the Jones matrix tomography of biological and medical samples. Jones matrix based signal processing and numerical estimator algorithm are then applied to obtain truly quantitative value of tissue birefringence. The clinical utility of JM-OCT is examined by...
In 2013, Tornado Spectral Systems introduced OCTANE-860, the first chip-based nanophotonic spectrometer for spectral-domain OCT. Technology advantages and challenges have been identified during development and a new strategy for optimizing performance will be discussed.
We introduce OCTANE, the first product line of chip-based spectrometers using silicon photonics for spectral domain optical coherence tomography (SD-OCT). It is well suited for low-cost, high-volume applications in both the medical and industrial fields.
Optical coherence tomography (OCT) is a powerful tool for three-dimensional (3D) and non-invasive investigation of eye. Polarization sensitive OCT (PS-OCT) is an extension of OCT and which provides birefringence tomography of in vivo tissue. The tissue birefringence is known to be strongly related to the microscopic structures of the tissue, and hence it is useful for tissue contrast imaging.
This presentation will describe several recent results relevant to photonic networks incorporating NV centers. The first experiment relates to the intrinsic properties of NV centers in bulk diamond. An important question is what temperatures are required to emit indistinguishable photons that carry information about the electron spin state of the NV center. While the long-lived coherence in the ground-state...
A silicon oxynitride based arrayed waveguide grating spectrometer was designed for on-chip spectral-domain optical coherence tomography systems. Transmission measurement results are promising for miniaturizing the current optical coherence tomography systems through integrated optics.
We fabricate and characterize photonic crystal microcavities in poly-crystalline diamond and observe quality factors up to 600. These structures are a first step towards controllable coupling of single N-V spins to single photons in a cavity-QED system in diamond, revealing new avenues for integrating logic with on-chip quantum communication.
