    2. Gabor-based fusion technique for Optical Coherence Microscopy

      Gabor-based fusion technique for Optical Coherence Microscopy
      We recently reported on an Optical Coherence Microscopy technique, whose innovation intrinsically builds on a recently reported - 2 μm invariant lateral resolution by design throughout a 2 mm cubic full-field of view - liquid-lens-based dynamic focusing optical probe [Murali et al.,Optics Letters 34, 145-147, 2009]. We shall report in this paper on the image acquisition enabled by this optical probe when combined with an automatic data fusion method developed and ...

    3. 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 ...

      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 ...

    5. Gabor domain optical coherence microscopy

      Gabor domain optical coherence microscopy
      In this paper, we present a developing technology targeted at clinical imaging, Gabor Domain Optical Coherence Microscopy (GD-OCM), which combines the high resolution imaging of optical coherence microscopy (OCM), high imaging speed of Fourier domain optical coherence tomography (FD-OCT), and invariant lateral resolution of our custom designed dynamic focusing objective. A high lateral resolution optical design of a dynamic-focusing optical probe with no moving parts, which provides an invariant resolution ...

    6. Optimization of the temporal performance of a deformable mirror for use in ophthalmic applications

      Adaptive optics (AO) is used to correct wavefront aberrations in light in real-time. An AO system is principally made up of three parts; a wavefront measuring device, a correction device, and a control algorithm to compute the residuals between the measured and a reference wavefront. Deformable mirr ... [Proc. SPIE 7139, 713912 (2008)] published Tue Dec 30, 2008.

    7. Effect of Blinking on Tear Volume After Instillation of Midviscosity Artificial Tears

      To determine by optical coherence tomography (OCT) the effect of blinking on ocular surface tear volume after instillation of artificial tears. Design Experimental study. Methods Normal human eyes (n = 21) were imaged to obtain dimensions of the tear film and menisci during blinking. The imaging was carried out immediately and five minutes after the instillation of 35 μl midviscosity artificial tears (1.0% carboxymethylcellulose; Refresh Liquigel; Allergan, Irvine, California, USA ...

    8. Detection of abnormalities in biological tissue using optical coherence tomography

      Detection of abnormalities in biological tissue using optical coherence tomography
      We studied the performance of an OCT imaging modality on the task of detecting an abnormality in biological tissue. Optical propagation in biological samples is dominated by scattering due to fluctuations in refractive index. We used the first order multiple scattering approximation to describe the ... [Proc. SPIE Int. Soc. Opt. Eng. 6849, 68490L (2008)] published Tue Feb 12, 2008.

    9. Method and apparatus for improving vision and the resolution of retinal images

      A method of and apparatus for improving vision and the resolution of retinal images is described in which a point source produced on the retina of a living eye by a laser beam is reflected from the retina and received at a lenslet array of a Hartmann-Shack wavefront sensor such that each of the lenslets in the lenslet array forms an aerial image of the retinal point source on a ...

  2. About University of Rochester

    University of Rochester

    University of Rochester, founded in 1850, is one of the nation's leading private universities. With just over 4,500 undergraduates, Rochester is one of the smallest and most collegiate in character among the top research universities

    Founded in 1850, UR offers degree programs at the bachelor's, master's, and doctoral levels, as well as in several professional disciplines. Its undergraduate and graduate degree programs in political science, business administration and music are among the best in the nation. The Institute of Optics at the university is also the oldest optics program in the U.S., having granted about half of the optics degrees in the nation.

    UR is a highly research oriented institution, hosting numerous centers of research, including the Laboratory for Laser Energetics, which boasts the most powerful ultraviolet laser in the world, and the University of Rochester Medical Center, featuring numerous biomedical and healthcare research facilities. Since 2005, UR with its affiliated Strong Health System, has been the largest employer in the Greater Rochester area.
