As in confocal SLO, light must pass through both a horizontal and a vertical scanning mirror before and after the eye is scanned to align the moving beam for eventual retinal faster images of the retina. Additionally, the light is reflected off of a deformable mirror before and after exposure to the eye to diffuse optical aberrations. The laser ...
[26] iPhone 14 Plus and iPhone 13. The iPhone 14 and iPhone 14 Plus have an identical design to the iPhone 13, although the US models do not have a physical SIM tray. The iPhone 14 and iPhone 14 Plus are available in six colors: Blue, Purple, Midnight, Starlight, Yellow, and Product Red. [27]
The light reflected from the retina passes through the un-illuminated hole in the doughnut formed by the illumination system. As the light paths of the two systems are independent, there are minimal reflections of the light source captured in the formed image. The image forming rays continue towards the low powered telescopic eyepiece.

True Tone, which is activated by default, uses advanced sensors to change the colour and intensity of the iPhone screen to match the ambient light, resulting in more natural-looking images. The ambient light sensor decides how much light is available around the iPhone and other Apple products, such as the iPod and iPad. The device changes the ...
The third and fourth Purkinje images can be visible from within the eye itself. Light reflected away from the surfaces of the lens can in turn reflect back into the eye from the rear surface of the cornea. The first and fourth Purkinje images are used by some eye trackers, devices to measure the position of
The visual system is organized hierarchically, with anatomical areas that have specialized functions in visual processing. Low-level visual processing is concerned with determining different types of contrast among images projected onto the retina whereas high-level visual processing refers to the cognitive processes that integrate information from a variety of sources into the visual ...
A traditional false-color satellite image of Las Vegas. Grass-covered land (e.g. a golf course) appears in red. In contrast to a true-color image, a false-color image sacrifices natural color rendition in order to ease the detection of features that are not readily discernible otherwise – for example the use of near infrared for the detection of vegetation in satellite images.
