    2. In vivo deep tissue imaging using wavefront shaping optical coherence tomography

      In vivo deep tissue imaging using wavefront shaping optical coherence tomography
      Multiple light scattering in tissue limits the penetration of optical coherence tomography (OCT) imaging. Here, we present in vivo OCT imaging of a live mouse using wavefront shaping (WS) to enhance the penetration depth. A digital micromirror device was used in a spectral-domain OCT system for complex WS of an incident beam which resulted in the optimal delivery of light energy into deep tissue. Ex vivo imaging of chicken breasts ...

    3. Apparatus and method for generating tomography image

      Apparatus and method for generating tomography image
      A method of generating a tomography image includes performing a depth scan on one spot on a surface of a subject using modulated light received from a spatial light modulator, obtaining depth scan data for each of a plurality of patterns of the spatial light modulator by repeating the depth scan on the spot for each of the plurality of patterns, forming a matrix R representing a vector space based ...

      In vivo deep tissue imaging using wavefront shaping optical coherence tomography
      Multiple light scattering in tissue limits the penetration of optical coherence tomography (OCT) imaging. Here, we present in-vivo OCT imaging of a live mouse using wavefront shaping to enhance the penetration depth. A digital micro-mirror device (DMD) was used in a spectral-domain OCT system for complex wavefront shaping of an incident beam which resulted in the optimal delivery of light energy into deep tissue. Ex-vivo imaging of chicken breasts and ...

    6. Complex wavefront shaping for optimal depth-selective focusing in optical coherence tomography

      Complex wavefront shaping for optimal depth-selective focusing in optical coherence tomography
      We report on an approach to exploit multiple light scattering by shaping the incident wavefront in optical coherence tomography (OCT). Most of the reflected signal from biological tissue consists of multiply scattered light, which is regarded as noise in OCT. A digital mirror device (DMD) is utilized to shape the incident wavefront such that the maximal energy is focused at a specific depth in a highly scattering sample using a ...
