      Blood flow velocity vector field reconstruction from dual-beam bidirectional Doppler OCT measurements in retinal veins

      In this paper, we demonstrate the possibility to reconstruct the actual blood flow velocity vector field in retinal microvessels from dual-beam bidirectional Doppler optical coherence tomography measurements. First, for a better understanding of measured phase patterns, several flow situations were simulated on the basis of the known dual beam measurement geometry. We were able to extract the vector field parameters that determine the measured phase pattern, allowing for the development of an algorithm to reconstruct the velocity vector field from measured phase data. In a next step, measurements were performed at a straight vessel section and at a venous convergence ...

    2. The Arden Photonics OCT validation Phantom

      The Arden Photonics OCT validation Phantom

      The Arden Photonics OCT validation Phantom has been developed to assure the performance standards of your instruments throughout their life. This unique product uses a laser-inscribed calibration pattern embedded in a stable silica substrate, allowing inspection with an optical microscope. Independent verification can therefore, easily be used to check the accuracy of the phantom when conducting tests. With the OCT validation Phantom from Arden Photonics, you can be assured of the accuracy of your OCT images. Features and benefits: Four different patterns in one small slide gives comprehensive assessment of your OCT instrumentation Patterns laser-inscribed in silica for excellent stability ...

      John S. Werner, UC Davis neuroscientist recognized for color vision and aging contributions

      John S. Werner, a UC Davis neuroscientist and international authority on visual perception, has been selected to receive the 2015 Verriest Medal from the International Colour Vision Society for his contributions to understanding the structural and functional basis of color vision, how and why vision changes across the life span, and factors that contribute to loss of vision associated with disease. He will receive the award at the society’s biennial symposium in Sendai, Japan, in July.
