    1. Simultaneous dual-band optical coherence tomography in the spectral domain for high resolution in vivo imaging

      Simultaneous dual-band optical coherence tomography in the spectral domain for high resolution in vivo imaging

      ptical coherence tomography (OCT) in the spectral domain is demonstrated simultaneously at two wavelength bands centered at 800 nm and 1250 nm. A novel commercial supercontinuum laser is applied as a single low coherence broadband light source. The emission spectrum of the source is shaped by optical and spatial filtering in order to achieve an adequate double peak spectrum containing the wavelength bands 700 - 900 nm and 1100 - 1400 nm for dual-band OCT imaging and thus reducing the radiation exposure of the sample. Each wavelength band is analyzed with an individual spectrometer at an A-scan rate of about 12 kHz ...

The emission spectrum of the source is shaped by optical and spatial filtering in order to achieve anadequate double peak spectrum containing the wavelength bands 700 - 900nm and 1100 - 1400 nm for dual-band OCT imaging and thus reducing theradiation exposure of the sample. Each wavelength band is analyzed with anindividual spectrometer at an A-scan rate of about 12 kHz which enablesreal-time imaging for the ...

    3. Resonant Doppler imaging with common path OCT

      Resonant Doppler flow imaging based on optical coherence tomography (OCT) is a recently developed imaging modality that provides, besides the structural information, dynamic blood flow information. We show that this method can be applied to a common path OCT system by mounting the mirror in the reference arm on a small piezo actor leading to a simpler and more stable system design. Besides the known 3 state cycle, we describe other cycles with any number of states leading to higher measurement speed or larger velocity range. The hysteresis of the piezo actor is compensated by applying an optimized electrical signal ...

    4. Effects of axial, transverse, and oblique sample motion in FD OCT in systems with global or rolling shutter line detector

      This study deals with effects on the interference signal caused by axial, transverse, and oblique motion in spectrometer-based Fourier-domain optical coherence tomography (FD OCT). Two different systems are compared--one with a global shutter line detector and the other with a rolling shutter. We ... [J. Opt. Soc. Am. A 25, 2791-2802 (2008)]
