Übersetzung für "Retinal image" in Deutsch

Apparent source is the real or virtual object that forms the smallest possible retinal image.

The light point pattern produced on the retina 20 is depicted by means of a half mirror 16 via an ophthalmoscope lens 22 and an objective 24 for the retinal image onto a sensor surface 28 of a solid-state image camera (CCD camera) in order to process the resulting light point pattern for calculation.

It detects errors of higher order by the specific wavefront technology. These errors have a high impact on the quality of the retinal image.

In contrast, in the case of the magnification of the visual angle, that angle is relevant at which the retinal image is seen from the entrance pupil when the eye is held still.

For example, the information system according to the invention could scan a retinal reflex image of the ambient light incident on the retina of an eye in the visible spectral range simultaneously with an image of the retinal structures emitting in the infrared range, in order to learn the region of the environment at which the portion of the eye with the sharpest vision is momentarily directed.

The curvature and thus also the refractive power of the cornea or lens differs in different meridians (axes) and the resulting retinal image is again blurry and deformed.

This may occur due to abnormalities in retinal image detection, retinal focusing, optic nerve transmission, or simply the central nervous system’s inability to interpret images correctly.

This product provides ultra resolution retinal image with the binocular indirect ophthalmoscope during clinical practice or in the operating room.

However, for the imaging through the spectacle lens and creating the retinal image, the magnification and the distortion play a decisive role: They quantify the dimensional changes of an object when looking through the spectacle lens.

The evaluation of retinal images is performed by ophthalmologists based on standardized criteria.

Have you run a retinal imaging scan?

The retinal exam can be completed in a quarter of a second and does not require pupil dilation, whereas conventional retinal imaging methods take longer and are more invasive and less patient-friendly.

An additional fine adjustment of convergence can take place with the aid of the fusion by which amalgamation of the two retinal images is made possible despite the fact that they are not formed on exactly corresponding areas of the retina (fall on disparate points).

Ideal for retinal and external imaging and associated interpretation, Pictor’s low system price results in a short payback period.

Large distortion differences between the left and the right spectacle lens disturb the binocular fusion (merger) of the two retinal images in the brain because the images in the left and the right eye are no longer similar geometrically.

In seeing any object, our eyes and therefore our retinal images are reacting to the object by shifting twenty times a second, and yet we see an unshifting stable object with no consciousness whatever of the succession of different inputs or of putting them together into the object.

Fixed objects produce retinal images of varying shapes, sizes and brightness. Due to changes in lighting, distance or perspective, this indicates that mechanisms must exist to identify these objects and their properties and to perceive them as being constant.

This allows us to analyze how retinal images are processed collectively by neural networks in the visual pathway.
