An outfit called Optibrand uses a retinal scanning system with a global positioning system to track individual cattle, both to verify that they're from the U.S., and where and what they've eaten in case of mad cow disease.
For more than 18 years he has been developing technology to use a retinal laser scan to identify eye disease, including new approaches to identifying amblyopia in young children using a noninvasive, rapid diagnostic scan.
Because the technology uses a scanning beam to paint the image on the retina, Microvision calls a device using this technology a retinal scanning display -- not to be confused with the biometric technology of retinal scanning, which detects the distinctive pattern of blood vessels on the retina, a pattern that can be analyzed to identify someone, similar to the way fingerprints are used.
"I see us moving away from a card we wave at a device to a retinal scan, a fingerprint identification.
A retinal scanning system consisting of imaging lenses and an X-Y galvanometer pair was used in the sample arm.
Fluorescein angiograms and ICGA were performed using a confocal scanning laser ophthalmoscope (Heidelberg Retinal Angiograph (HRA), HRA-C/HRA2/HRA Spectralis, Heidelberg Engineering, Germany).
Fluorescein angiogram (FA) and indocyanine green angiogram (ICG) were performed using a scanning laser ophthalmoscope (Heidelberg Retinal Angiography; Heidelberg Engineering, Heidelberg, Germany) at baseline and every 3 months.
Both retinal whole mounts and tissue sections were observed using a confocal scanning laser microscope (LSM510 META; Carl Zeiss, Jena, Germany).
The visuals make it appear that the billboards are using retinal scans to identify the unlucky Anderton.
To visualize retinal pigment epithelial cells in vivo by fundus autofluorescence imaging using a confocal scanning laser ophthalmoscope.
