New Biomedical Optics Data Have Been Reported by Researchers at Duke University (Optimization of confocal scanning laser ophthalmoscope design)

August 20, 2014

By a News Reporter-Staff News Editor at Biotech Week -- A new study on Biotechnology is now available. According to news reporting from Durham, North Carolina, by NewsRx journalists, research stated, "Confocal scanning laser ophthalmoscopy (cSLO) enables high-resolution and high-contrast imaging of the retina by employing spatial filtering for scattered light rejection. However, to obtain optimized image quality, one must design the cSLO around scanner technology limitations and minimize the effects of ocular aberrations and imaging artifacts."

The news correspondents obtained a quote from the research from Duke University, "We describe a cSLO design methodology resulting in a simple, relatively inexpensive, and compact lens-based cSLO design optimized to balance resolution and throughput for a 20-deg field of view (FOV) with minimal imaging artifacts. We tested the imaging capabilities of our cSLO design with an experimental setup from which we obtained fast and high signal-to-noise ratio (SNR) retinal images. At lower FOVs, we were able to visualize parafoveal cone photoreceptors and nerve fiber bundles even without the use of adaptive optics."

According to the news reporters, the research concluded: "Through an experiment comparing our optimized cSLO design to a commercial cSLO system, we show that our design demonstrates a significant improvement in both image quality and resolution."
