Space-division multiplexing optical coherence tomography.
High speed, high resolution and high sensitivity are desirable for optical coherence tomography (OCT). Here, we demonstrate a space-division multiplexing (SDM) technology that translates long coherence length of a commercially available wavelength tunable laser into high OCT imaging speed. We achieved an effective 800,000 A-scans/s imaging speed using a 100,000 Hz tunable vertical cavity surfac...
متن کاملWide-field high-speed space-division multiplexing optical coherence tomography using an integrated photonic device.
Space-division multiplexing optical coherence tomography (SDM-OCT) is a recently developed parallel OCT imaging method in order to achieve multi-fold speed improvement. However, the assembly of fiber optics components used in the first prototype system was labor-intensive and susceptible to errors. Here, we demonstrate a high-speed SDM-OCT system using an integrated photonic chip that can be re...
متن کاملWavelength and Space Code Division Multiplexing in Optical Tomography
Optical Tomography aims at reconstructing one or more spatially variable coefficients in a volume from measurements of propagation of near infrared light fluxes at its surface. The propagation of near infrared photons in biological media has a diffusive nature, as photons are absorbed and massively scattered by tissues, and coefficients are reconstructed by post-processing algorithms. Time reso...
متن کاملMultimodal noncontact photoacoustic and optical coherence tomography imaging using wavelength-division multiplexing.
We present multimodal noncontact photoacoustic (PA) and optical coherence tomography (OCT) imaging. PA signals are acquired remotely on the surface of a specimen with a Mach-Zehnder interferometer. The interferometer is realized in a fiber-optic network using a fiber laser at 1550 nm as the source. In the same fiber-optic network, a spectral-domain OCT system is implemented. The OCT system util...
متن کاملMultiplexing-based polarization sensitive en-face optical coherence tomography.
We present a time-domain polarization-sensitive (PS) optical coherence tomography configuration operating at 830 nm, equipped with multichannel acousto-optic deflectors and single photodetectors. The system is used to simultaneously acquire interference information from multiple PS channels and to enable measurement and imaging of backscattered intensity to create both PS and polarization insen...
