    摘要: An adaptive optics scanning laser opthalmoscopes is introduced to produce non-invasive views of the human retina. The use of dual deformable mirrors improved the dynamic range for correction of the wavefront aberrations compared with the use of the MEMS mirror alone, and improved the quality of the wavefront correction compared with the use of the bimorph mirror alone. The large-stroke bimorph deformable mirror improved the capability for axial sectioning with the confocal imaging system by providing an easier way to move the focus axially through different layers of the retina.

    摘要: This invention permits retinal images to be acquired at high speed and with unprecedented resolution in three dimensions (4×4×6 μm). The instrument achieves high lateral resolution by using adaptive optics to correct optical aberrations of the human eye in real time. High axial resolution and high speed are made possible by the use of Fourier-domain optical coherence tomography. Using this system, we have demonstrated the ability to image microscopic blood vessels and the cone photoreceptor mosaic.

    摘要: Meter electronics (20) for quantifying a fluid being transferred is provided. The meter electronics (20) includes an interface (201) configured to communicate with a flowmeter assembly of a vibratory flowmeter and receive a vibrational response and a processing system (203) coupled to the interface (201). The processing system (203) is configured to measure a volume flow and a density for a predetermined time portion of the fluid transfer, determine if the fluid transfer is non-aerated during the predetermined time portion, if the predetermined time portion is non-aerated then add a volume-density product to an accumulated volume-density product and add the volume flow to an accumulated volume flow, and determine a non-aerated volume-weighted density for the fluid transfer by dividing the accumulated volume-density product by the accumulated volume flow.
