    1. Adaptive optics and the eye (super resolution OCT)

      Adaptive optics and the eye (super resolution OCT)
      The combination of adaptive optics (AO) and optical coherence tomography (OCT) was first reported 8 years ago and has undergone tremendous technological advances since then. The technical benefits of adding AO to OCT (increased lateral resolution, smaller speckle, and enhanced sensitivity) increase the imaging capability of OCT in ways that make it well suited for three-dimensional (3D) cellular imaging in the retina. Today, AO–OCT systems provide ultrahigh 3D resolution (3 × 3 × 3 μm3) and ultrahigh speed (up to an order of magnitude faster than commercial OCT). AO–OCT systems have been used to capture volume images of retinal structures ...

    2. Morphometric analysis of the optic nerve head with optical coherence tomography

      Morphometric analysis of the optic nerve head with optical coherence tomography
      Optical Coherence Tomography is a powerful tool for diagnostic imaging of the ocular posterior chamber. Recent advances in OCT technology have facilitated acquisition of high resolution volumetric images of the retina and optic nerve head. In this report, we investigate optic nerve head imaging in humans using a home-built laboratory grade OCT system in the 800nm wavelength region. We also introduce the development of a computational model of the optic nerve head morphology in order to study physiological changes which may be associated with elevated intra-ocular pressure.

    3. eXtreme chirped pulse oscillator operating in the nanosecond stretched pulse regime.

      Related Articles eXtreme chirped pulse oscillator operating in the nanosecond stretched pulse regime. Opt Express. 2008 Mar 31;16(7):4766-73 Authors: Lee S, Mandridis D, Delfyett PJ An eXtreme Chirped Pulse Oscillator (XCPO) implemented with a Theta cavity and based on a semiconductor optical amplifier (SOA) is presented for generating 10 ns frequency-swept pulses and 3.6 ps compressed pulses directly from the oscillator. In this experiment, we show the two distinct characteristics of the XCPO which are the scalability of the output energy and the mode-locked spectrum. By using these characteristics, we obtain a pulse energy of 58 ...
