    2. Single detector-based absolute velocity measurement using spectral domain Doppler optical coherence tomography

      Single detector-based absolute velocity measurement using spectral domain Doppler optical coherence tomography
      We propose an approach for absolute velocity measurement where the use of a beam displacer provides two orthogonal linearly polarized beams to probe the sample simultaneously at two different incidence angles. The approach helps remove the cross talk image and facilitates single detector-based Fourier domain Doppler velocity measurement. The system has been characterized by quantifying absolute flow velocity in a flow phantom.

    3. Swept-source digital holography to reconstruct tomographic images

      Swept-source digital holography to reconstruct tomographic images
      We present what we believe to be a new method of swept-source digital holography using a superluminescent diode (SLD) as a broadband light source and an acousto-optic tunable filter (AOTF) as a frequency tunable device. The swept source consists of an SLD as a broadband source in conjunction with the AOTF as the frequency tuning device in the wavelength range of 800–870 nm. Since the AOTF is an electronically ...
