  1. Advanced Polymer GRIN Optics Lens Mimics Human Eye

    Science fiction fans are familiar with Steve Austin and Geordi LaForge.  CLiPS researchers have been working in areas that previously might have been viewed as science fiction with the development of an optical lens that mimics the way human eye lenses work. This research may lead to more natural acting implantable lenses, as well as providing applications for optical equipment and surveillance technology.

    A recent article in Optics Express described research coming out of CLiPS technology that has led to advanced polymer, multi-layered lenses.  This article published online by The Optical Society describes the research and its potential, quoted here in part:

    “The research team’s new approach was to follow nature’s example and build a lens by stacking thousands and thousands of nanoscale layers, each with slightly different optical properties, to produce a lens that gradually varies its refractive index, which adjusts the refractive properties of the polymer.”

    This story was picked up by UPI and, understandably, has generated a great deal of interest both in the technical and popular press.

  2. The Persistence of Data

    I recently came across this post on how long data will last here at Seagate’s blog:

    “In the past, I posted about the shelf-life of each storage medium, granted it’s not forever, but 100 years is pretty good. A lot better than disk drives and tape.

    Floppy disks: up to 5 years

    Hard Drives: up to 10 years

    Magnetic tape: up to 20 years

    Optical disks: up to 100 yrs

    SSD and Flash: up to 100 yrs

    Stone tablets: up to 10,000 yrs”

    I found it particularly interesting because he references a redOrbit article on optical data storage technology pioneered in Prof. Ken Singer’s lab in CLiPS.
