Standard photographic objectives are made such that their field of view is similar to that of the human eye – with a full horizontal angle around 50°, when considering the range with reasonable sharp imaging. When changing the zoom setting of an objective, the field of view will change, of...

5.4Photographs vs. Human Vision Photographs are often considered to be accurate portrayals of visual scenes. However, photographs do not record images in the same way the human eye would respond to the identical scenes. For the following discussion, we ignore special techniques, such as filters,...
It is thus clear that, this human security installations of double vision angle X ray, the design is placed in two sets of imaging system of different positions, adopts the double vision angle in the human systemic while of scanning, also can carry out human local scanning, and the loss ...
I don't really know too much about the human body, but this is my rough understanding of how vision works: light comes from a source, like the sun, it hits an object, and then if it's of the right frequency it's reflected by the object and then enters one of your two eyes, whe...
Simul- taneous realization of a large aperture and high NA is still a big challenge. Nevertheless, a small-aperture achromatic metalens array has been applied in full-color light-field imaging by Lin et al. [79]. In addition to dispersion control, asymmetric photonic spin–orbit interactions, ...
This may limit vision and makes it difficult to see fine retinal details in ophthalmoscopy. We designed and built a two-triplet system for correcting the average longitudinal chromatic aberration of the eye while keeping a reasonably wide field of view. Measurements in real eyes were conducted to...
PROCESS AND DEVICE FOR THE TRAINING OF HUMAN VISION The present invention concerns a process for training the visual system of a human by presenting optical stimuli to said human, said stimuli being presented to a zone within the intact visual field of said human and to a zone outside the....
