  2. Retinal scan - Wikipedia

    en.wikipedia.org/wiki/Retinal_scan

    Retinal scan. A retinal scan is a biometric technique that uses unique patterns on a person's retina blood vessels. It is not to be confused with other ocular-based technologies: iris recognition, commonly called an "iris scan", and eye vein verification that uses scleral veins.

  3. Scanning laser ophthalmoscopy - Wikipedia

    en.wikipedia.org/wiki/Scanning_laser_ophthalmoscopy

    Scanning laser ophthalmoscopy (SLO) is a method of examination of the eye. It uses the technique of confocal laser scanning microscopy for diagnostic imaging of the retina or cornea of the human eye. As a method used to image the retina with a high degree of spatial sensitivity, it is helpful in the diagnosis of glaucoma, macular degeneration ...

    en.wikipedia.org/wiki/Biometric_device

    Iris scanner in action to identify people. A biometric device is a security identification and authentication device. Such devices use automated methods of verifying or recognising the identity of a living person based on a physiological or behavioral characteristic. These characteristics include fingerprints, facial images, iris and voice ...

    en.wikipedia.org/wiki/Virtual_retinal_display

    Virtual retinal display. A diagram showing the workings of the virtual retinal display. A virtual retinal display (VRD), also known as a retinal scan display (RSD) or retinal projector (RP), is a display technology that draws a raster display (like a television) directly onto the retina of the eye.

  6. Vein matching - Wikipedia

    en.wikipedia.org/wiki/Vein_matching

    The retinal scanner is more reliable than the vascular scanner, but is less widely used because of its intrusive nature. People generally are uncomfortable exposing their eyes to an unfamiliar source of light, and retinal scanners are more difficult to install than vascular scanning equipment, since variations in angle of height and face in ...

  7. Optical coherence tomography angiography - Wikipedia

    en.wikipedia.org/wiki/Optical_Coherence...

    OCTA scan time is now around three seconds, however, saccadic eye movement still causes a low signal-to-noise ratio. This is where SSADA proves to be very advantageous as it is able to greatly improve SNR by averaging the decorrelation across the number of B-scans, making the microvasculature of the retina visible.

    Virtual retinal display (VRD) – Also known as a retinal scan display (RSD) or retinal projector (RP), is a display technology that draws a raster display (like a television) directly onto the retina of the eye - developed by MicroVision, Inc. [38] The Technical Illusions castAR uses a different technique with clear glass. The glasses have a ...

  9. Stereoscopy - Wikipedia

    en.wikipedia.org/wiki/Stereoscopy

    A virtual retinal display (VRD), also known as a retinal scan display (RSD) or retinal projector (RP), not to be confused with a "Retina Display", is a display technology that draws a raster image (like a television picture) directly onto the retina of the eye. The user sees what appears to be a conventional display floating in space in front ...
