    1. Sub-cellular resolution imaging with Gabor domain optical coherence microscopy

      Sub-cellular resolution imaging with Gabor domain optical coherence microscopy
      Optical Coherence Microscopy (OCM) utilizes a high NA microscope objective in the sample arm to achieve an axially and laterally high resolution OCT image. An increase in NA, however, leads to a dramatically decreased depth of focus (DOF), and hence shortens the imaging depth range so that high lateral resolution is maintained only within a small depth region around the focal plane. One solution to increase the depth of imaging while keeping a high lateral resolution is dynamic-focusing. Utilizing the voltage controlled refocus capability of a liquid lens, we have recently presented a solution for invariant high resolution imaging using ...

      Gabor domain optical coherence microscopy
      Optical Coherence Microscopy (OCM) utilizes a higher NA microscope objective in the sample arm of a low coherence interferometer than in Optical Coherence Tomography (OCT) to achieve axially and laterally high-resolution optical tomographic images. An increase in NA, however, leads to a dramatically decreased depth of focus (DOF), and hence shortens the imaging depth range so that high lateral resolution is maintained only within a small depth region around the focal plane. One solution to increase the depth of imaging while keeping a high lateral resolution is dynamic-focusing. Utilizing the voltage controlled refocus capability of a liquid lens, we have ...

    3. Gabor domain optical coherence microscopy

      Gabor domain optical coherence microscopy
      Optical Coherence Microscopy (OCM) is an emerging technology capable of depth sectioning of biological tissue at the micrometer scale. In this paper, we propose a developing technology we call Gabor Domain Optical Coherence Microscopy (GD-OCM), whose innovation is two folds: (1) A high lateral resolution optical design of a dynamic-focusing optical probe with no moving parts, which provides an invariant resolution of currently 3 ┬Ám across a 2mm full-field of view and 2mm imaging depth by design; (2) An acquisition scheme (using the probe) that is capable of performing automatic data fusion to render an in-focus high resolution image throughout ...

    4. Thermoelastic optical Doppler tomography of biological tissues

      Thermoelastic optical Doppler tomography of biological tissues
      In this presentation, we demonstrate a novel optical tomography technique, thermoelastic optical Doppler tomography (ODT). Short laser pulses are used to generate thermoelastic waves in biological samples. Optical phase variations in response to wave propagation are detected using ODT. It is shown that areas of different elastic property in the phantom can be clearly resolved.
