High-resolution mid-infrared optical coherence tomography with kHz line rate

چکیده
We report on Mid-infrared (MIR) OCT at 4 $\mu$m based collinear sum-frequency upconversion and promote the A-scan scan rate to 3 kHz. demonstrate increased imaging speed for two spectral realizations, one providing an axial resolution of 8.6 $\mu$m, a record 5.8 $\mu$m. Image performance is evaluated by sub-surface micro-mapping plastic glove real-time monitoring CO$_2$ in parallel with imaging.

Ultrahigh-resolution optical coherence tomography.
In the past two decades, optical coherence tomography (OCT) has been established as an adjunct diagnostic technique for noninvasive, high-resolution, cross-sectional imaging in a variety of medical fields. The rapid development of ultrabroad bandwidth light sources has recently enabled a significant improvement in OCT imaging resolution, demonstrating the potential of OCT to accomplish its orig...
متن کاملMid-infrared interferometry with high spectral resolution
The Infrared Spatial Interferometer (ISI) is a three telescope interferometer system that operates near 11 microns wavelength using heterodyne detection with CO2 lasers as local oscillators. Stellar measurements have been made using consistent instrumentation for 20 years, allowing comparisons of stellar sizes of red giant and Mira stars over time intervals which are long in comparison to stell...

Introduction:Visualization of inner ear structures is a valuable strategy for researchers and clinicians working on hearing pathologies. Optical coherence tomography (OCT) is a high-resolution imaging technology which may be used for the visualization of tissues. In this experimental study we aimed to evaluate inner ear anatomy in well-prepared human labyrinthine bones.Materials and Methods:Thr...
متن کاملHigh-resolution imaging of gynecologic neoplasms using optical coherence tomography.
BACKGROUND A modality capable of imaging the female reproductive tract, at or near the cellular level, could lead to the detection of diseases at earlier stages than currently possible. Optical coherence tomography achieves high resolutions in the cellular range (4-20 microm) and could accomplish that level of detection. METHOD Optical coherence tomography imaging of gynecologic tissue was st...
متن کاملLarge Field, High Resolution Full-Field Optical Coherence Tomography
We present a benchmark pilot study in which high-resolution Full-Field Optical Coherence Tomography (FF-OCT) was used to image human breast tissue and is evaluated to assess its ability to aid the pathologist's management of intra-operative diagnoses. FF-OCT imaging safety was investigated and agreement between FF-OCT and routinely prepared histopathological images was evaluated. The compact se...
